Pennsylvania's wiretapping law is a "two-party consent" law. Pennsylvania makes it a crime to intercept or record a telephone call or conversation unless all parties to the conversation consent. See 18 Pa. Cons. Stat. § 5703 (link is to the entire code, choose Title 18, Part II, Article F, Chapter 57, Subchapter B, and then the specific provision).
This is similar to what happened here http://www.popehat.com/2010/04/14/embarrass-a-cop-in-maryland-thatll-be-five-years-in-jail/

However on September 27, 2010, some criminal charges against Graber were dropped. Harford County Circuit Court Judge Emory A Plitt Jr. dismissed four of the seven charges filed against Anthony Graber, leaving only traffic code violations. The judge ruled that Maryland's wire tap law allows recording of both voice and sound in areas where privacy cannot be expected and that a police officer on a traffic stop has no expectation of privacy.

This situation is no different.
