Bob you still haven't thought this idea through any further, its a terrible idea. I'll explain why but its probably going to be a bit long but bear with me and you'll understand why you are 'dead' wrong.

So "Bob's Law" is now in effect, Mr Bandito is in the back of a Taxi committing an armed robbery demanding the taxi driver hand over his money and valuables. Mr Bandito notices that the taxi driver has been getting looks at him in the rear view mirror. While the driver is nervously fumbling and trying to pull out the wallet he is sitting on in his back pocket, it crosses Mr Bandito's mind that "Bob's Law" is in effect and as soon as the driver hands him the wallet over Mr Bandito shoots and kills the taxi driver.

Mr Bandito did this because the punishment (death) is the same for robbing the driver as it is for murdering the driver. An alive taxi driver would make it easier for the police to catch him and Mr Bandito is of the same propensity as the folks that passed this law and so to him it now makes sense to kill all witnesses of an armed robbery as procedure, as the penalty is the same either way.

¿I keep seeing Trump stuff on places like here and facebook etc, are Americans panicking?

"Those willing to rob this way should be put down. "

Errr we've already tried that it usually turns out so worse for the victims.
