In Pennsylvania carrying a gun is not reasonable suspicion of a crime and not justification for a stop and search or a detainment.

Open Carry is legal in Philadelphia with a valid license to carry firearms; openly carrying on foot is legal without a license everywhere else in Pennsylvania.

"On a Sunday afternoon, a Pennsylvania resident was walking up Frankford Avenue in Philadelphia, bound for an auto parts store, and happened to be legally openly carrying a Glock pistol on his hip, under PA state law.

A passing Philadelphia Police officer saw his walking up the road, pulled over his squad car in the middle of the busy street, and drew his weapon on the man, threatening to kill him multiple times if he moved.

The man was arrested, stripped of his possessions, and thrown in the paddywagon, while several Philadelphia Police officers made multiple phones calls to try and find out what law they think he broke.

In the end, they discovered that he was in violation of no laws, and was sent on his way, after having been illegally arrested for 45 minutes and his 4th Amendment rights blatantly violated."
