Walleye Tournament Cheaters Got Busted! Clear video

spawnflagger says...

I didn't think it was possible, but looked it up (found this) and modern metal detectors can detect lead.
So there's really little reason the tournament judges weren't running a metal detector over every fish.
(a x-ray would be more definitive, but way more expensive and can't be battery powered)

The biggest wtf here is that they haven’t been checking these fish all this time?

Holy fucking sheep shit, the importance of the testimony given today!

Trump knew his crowd was seriously armed, and encouraged turning off the metal detectors, just for one. I’m sure you’re waiting for Glen Beck and Alex Jones to tell you how to spin it all….probably just by saying she’s just another liar and secret liberal, and making certain you don’t watch for yourself. Best you’ve got, and it’s so very little.

I would say “ Wake up from you delusional dream and accept reality.”, but I know not only are you incapable, you don’t want to. The lies are so much more comfortable than reality for you.

PS- I still wonder, are you even one bit embarrassed at getting caught trying to say Democrats support the KKK when David Duke is an actual long time Republican representative?!

Edit: a little reminder….Trump’s people take the fifth when asked if they believe in the peaceful transfer of power….

how much has been spent on investigation Trump ? 40 ---- 60 Million and still nothing of importance has come to light.

Wake up from you delusional dream and accept reality.

Mom arrested after posing as 7th grade daughter in school

BSR says...

Some of the more recent United States Governmental statistics indicate that about 2% of elementary schools in the U.S. use metal detectors, 7% of middle schools, and 10% of high schools. This is a fairly low number, with literally only 1-in-10 high schools utilizing metal detectors within the country. Aug 13, 2019
-----------------------------------------
I understand that "probably" all school shootings have been committed by real students. Students with hatred issues, respect issues, power issues or whatever. She got away with acting as a student and penetrating the security or lack of it. Granted I can't see just anyone getting away with her plan by "acting" as a student but she was able to gain unfettered access.

With 3D printers getting more sophisticated, metal detectors are not a catch all. I also think there can be better ways to recognise mental issues earlier to reduce the threat of would be killers. It's not foolproof but after a shooting there were usually signs of a violent nature of the shooter before hand.

Yes she may be a criminal but she was unarmed and had no violent intentions and was aware of the risks of her actions but still felt more was needed to be done. I believe more needs to be done keeping the public safe from people that want to cause harm just because they have the power to do it. That includes bullies who don't pick up guns but rather create rage in innocent people.

My initial comment was due to @jimnms comment which seemed to imply the woman was merely an attention whore and overlooked what her real intentions may have been.

EDIT: I also think your decision to not have children and perhaps grandchildren could have a HUGE impact on reducing the number of children killed or wounded anywhere in the world. If only...

If true, and she pleads guilty to whatever charges they levied, then maybe, but if she fights them in court that altruistic assumption is out the window and she gets another strike for wasting the court's time (and our money) on a case she knows she's definitely guilty of.

We assume she's being honest and this was just a security test, but more than one mother has murdered their daughter's high school rival. I'm not willing to take a criminals word when they suggest they were only trespassing as a public service, not falsifying their identity to hide from crimes they're planning.

I don't think school shooters have ever disguised themselves as students when they weren't...and she didn't bring a gun sized piece of metal through the metal detectors....so she wasn't testing against how easy it would be for armed intruders, only unarmed imposters.

However, schools are becoming more secure in light of school shootings but more needs to be done and this was the point she was making. She was able to bypass the lax security at the school and was willing to pay the price for putting it to the test.

She wasn't there to kill anyone, just the poor security measures. If anything the school board or whoever should be fined.

Do you think a school shooter gives a shit about their rights to be in a school?

Hasan Minhaj takes a lie detector test

BSR says...

My mother was the most accurate lie detector EVER! My mother was the most forgiving mother EVER!

It's also possible I was the worst liar ever.

The teacher sent me home with a note for my parents.

Grreta Thunberg's Speech to World Leaders at UN

newtboy says...

If they get bored and stop listening, they'll get confused, won't they? I think they often get bored because they can't follow along, it's incredibly boring to have someone drone on using statistics and measurements you don't grasp and won't remember on a subject you also don't grasp.

I agree, but so far, measurements have consistently been outpacing the estimates, almost never the reverse.

What they tend to do is come from that incomplete data and incomplete analysis to model the absolute best case scenario to dictate policy, not the worst. That's absolutely what the U.N. report does, and it's not clear to most how much is left out, like infinitely better melting models (the measured melting in Greenland is already at the rate not predicted to be reached until 2075 in the UN's published estimations) and feedback loops we already see in action like melting methalhydrates and permafrost, both outgassing massive amounts of methane. Sane policy makers DO assume the absolute worst modeled outcome, then suggests policies to avoid it, at all cost when that worst case is extinction. Since measurements are consistently as bad or worse than the worst case scenario modeled, the only rational thing to do is assume that will continue and plan for the worst....you know, like they taught in preschool, hope for the best, prepare for the worst.

Your house burning down is an unlikely worst case scenario, but I bet you have smoke detectors, fire extinguishers, and support the fire department. Good planning is to assume you WILL have a fire and plan to minimize the damage.
Or, terrorist attacks. The likelihood you'll be killed in a terrorist attack is exceptionally low, but we spend untold billions and sacrifice liberties to combat a worst case but unlikely scenario.

Prudence is the better part of valor.

Edit: as to most problems society faces, I suggest they are likely ALL a function of overpopulation....no question imo when it comes to the apocalyptic problems. Pollution, resource mismanagement, ecological destruction, etc. None would be disastrous with 1/10 the population.

About 20 years ago, I thought it would be cool to do this in real time with police radar. You get a radar signal off your detector, but it's coming from a lamp post, keep speeding. If it's coming from that bush a 1/2 mile down, beside the road, slow down.

Dr. Christine Blasey Ford and Brett Kavanaugh Testify

ChaosEngine says...

Two things:
1: " once you are accused of sexual anything with a female, you are pretty much fucked"
unless you're running for president as a republican... then you're fine.

2: " it has been scientifically proven that lie detector tests are inherently flawed"
Completely agree with this. I cringe every time someone says that Ford took a polygraph. Those things are bullshit.

I DO feel that Kavanaugh should have the presumption of innocence. I have no idea if he actually did assault Ford, but the accusation alone merits investigation (even if he was guilty, the investigation probably wouldn't have turned up anything after so long).

Mordhaus said:

I feel that he probably won't make it. Sadly once you are accused of sexual anything with a female, you are pretty much fucked. There is no more innocent until proven guilty. Were I him, even though it has been scientifically proven that lie detector tests are inherently flawed, I would have volunteered to take one just to push past this.

On the flip side, the possible next nominee is Judge Amy Coney Barrett and there is precedent for them to completely skip the committee vote, so there is a good possibility that we can still get a conservative judge on the court. She has not been as harsh towards abortion rights either, so there is a silver lining.

Teacher Fed Up With Students Swearing, Stealing, And Destroy

JiggaJonson says...

I disagree. Pinpointing the problem isn't very hard if you have some idea of where to look.

As someone who was 'coming of age' in my profession when No Child Left Behind (NCLB) and its successor the Every Student Succeeds Act (ESSA), I can provide some insight into how these policies have been enacted and how both have been detrimental to the public education system as a whole. The former is a GWBush policy, and the latter is an Obama policy meant to mend the original law, so both liberals and conservatives are to blame to some degree, but both are based on the same philosophy of education and teacher-accountability.

There are some other mitigating factors and outside influences at work that should be noted: gun violence, the rise & ubiquity of the internet, and universal cell phone availability, all mostly concentrated in the past 10 years that play a large role. Cell phones, for example, are probably the worst thing to happen to education ever. They distract, they assist in cheating, they perpetuate arguments which can lead to physical altercations, and parents themselves advocate for their use "what if there's an emergency?!?!"

The idea of "teacher accountability" is the biggest culprit though.

Anecdotally, I've caught people cheating on papers. A girl in my honors English class basically plagiarised her entire final paper that we worked on for close to a month. The zero tanked her grade, which was already floundering, and the parent wanted to meet. I'd rather not go into detail to protect both the girl and my own anonymity, but suffice to say, all of the blame for this was aimed directly at me. How? Well I (apparently) "should have caught this sooner and intervened." Now, the final in that class is 8 pages long, I have ~125 students all working on it at the same time. but my ability to check something like that and my workload are beside the point. I'M NOT THE ONE WHO COPY PASTED A WIKIPEDIA ARTICLE AND DOCTORED IT UP SO IT COULD SQUEAK BY THE PLAGIARISM DETECTOR (shows she knew what she was doing, IMHO). Yet, I'm still the one being told that I was responsible for what happened.

Teacher-accountability SOUNDS like the right thing to do, but consider the following analogies

--Students are earning poor grades, therefore teachers should be demoted; put on probationary programs; lose some of their salaries; and if they do not improve their test scores, grades, and attendance; be terminated from their positions.

as to

--Impoverished people have poor oral hygiene/health, therefore their dentists should be forced to take pay cuts from insurance companies. If the patients continue to develop cavities and the like, the dentist should be forced to go for further training, and possibly lose his practice.

I have no control over attendance.
I have no control over their home life.
I have no control over children coming to school with holes in their shoes, having not eaten breakfast.

@Mordhaus the part about money grubbing could not be further from the truth.

I'll be brief b/c I know this is already too long for this forum, but Houton Mifflin, McGraw Hill, Etc. Book Company is facing a shortfall of sales in light of the digital age. It may be difficult to blame one entity, but that's a good place to start. They don't sell as many books, but guess who produces and distributes the standardized tests and practice materials? Those same companies who used to sell textbooks by the boatload.

When a student does poorly, they have to retest in order to recieve a diploma. $$$ if they fail again, they retest again and again there is a charge for taking the test and accompanying pretest materials. Each of which has its own fees that go straight to the former textbook companies. See: https://www.pbs.org/wgbh/pages/frontline/shows/schools/testing/companies.html

In short, there is an incentive for these companies to lobby for an environment where tests are taken and retaken as much as possible. Each time a student has to retest that's more $ in their pocket.

How can they create an enviorment that faccilitates more testing? Put all the blame on the educators rather than the students.

That sounds a little tin-foil-hat conspiracy theory-ish, but the lobbying they do is very real: https://www.washingtonpost.com/news/answer-sheet/wp/2015/03/30/report-big-education-firms-spend-millions-lobbying-for-pro-testing-policies/?utm_term=.
9af18f0d2064

That, combined with exceptions for charter/private schools where students have the option to opt-out of said testing is skewing the numbers in favor of all of these for-profit companies: http://sanchezcharter.org/state-testing-parent-opt-out/ << one example (you can't opt-out in a public school, at least in my state)

@bobknight33 idk if i'd call business-minded for-profit policies "liberal"

Mordhaus said:

Instead of focusing on who 'created' the problem, which I guarantee you cannot tie to any one specific group or ideology, we should be instead looking for a solution to the problem.

At some point we are going to have to quit beating our drums about 'bleeding heart' liberals or 'heartless money grubbing' republicans and work together. If we can't, then we deserve everything we have coming.

I'm surprised that he didn't think of a way to defeat a metal detector. Identifying hacks to solve skilled tasks with effort are an important part of puzzle making.
