I'm not sure what the realpolitik is behind bizarrely prosecuting him for something very few normal people are prosecuted for while not prosecuting him for the things he got away with just because of who he is -- in order to prove that the rule of law still exists.

No logic there.

From a totally naive perspective, I would just say it speaks to how cases are originated. There are probably a few people who have written books about drug addition describing a time period in which a record can be found of them purchasing a weapon. But I guess somebody said "go charge Little Biden with something because he's a well known violator."

Never forget also the simple angle of just attacking guns and painting guns as tools of violent crackheads.
