I've Figured It Out...

Crime ridden Philadelphia is very close to New Jersey, a state where you can be arrested for having a hollow point bullet in your pocket.

Hollow point bullets are defined as a weapon in and of themselves under New Jersey State statutes.

2C:39-3 Prohibited weapons and devices
f. Dum-dum or body armor penetrating bullets. (1) Any person, other than a law enforcement officer or persons engaged in activities pursuant to subsection f. of N.J.S.2C:39-6, who knowingly has in his possession any hollow nose or dum-dum bullet, or (2) any person, other than a collector of firearms or ammunition as curios or relics as defined in Title 18, United States Code, section 921 (a) (13) and has in his possession a valid Collector of Curios and Relics License issued by the Bureau of Alcohol, Tobacco and Firearms, who knowingly has in his possession any body armor breaching or penetrating ammunition, which means: (a) ammunition primarily designed for use in a handgun, and (b) which is comprised of a bullet whose core or jacket, if the jacket is thicker than.025 of an inch, is made of tungsten carbide, or hard bronze, or other material which is harder than a rating of 72 or greater on the Rockwell B. Hardness Scale, and (c) is therefore capable of breaching or penetrating body armor, is guilty of a crime of the fourth degree. For purposes of this section, a collector may possess not more than three examples of each distinctive variation of the ammunition described above. A distinctive variation includes a different head stamp, composition, design, or color.

New Jersey is also a state that will wrongfully imprison a citizen even when they follow state and federal laws. Fortunately, the new governor pardoned the innocent man after he had already served some time.

It appears that the stupidity has now been transferred by close proximity osmosis, or maybe they share a common reservoir, and there's something in the water.
