If jurors aren't acknowledging a person's gang affiliation from something so obvious as a gang tattoo then those people are the problem, not the law.

I give you that SOME of those tattoos may seem ambiguous to someone who isn't enducated on gangs, but there are plenty of examples there that are PAINFULLY OBVIOUS they are gang members...
Plenty of gang members take extreme pride in their gang and have no problems openly expressing their affiliation (see photos from link above), even to law enforcement.
The violence in Chicago has very little to do with the NRA or any legal gun owners. Gangs are
stealing their guns from people, gun laws have no effect on them having one or carrying one. Antagonizing the NRA will not stop or even remotely hinder criminal gangs from acquiring firearms.
The
law has worked just fine, the link I provided lists 36 convictions in the first year, I cant find any info on how many since then.
The problem is Judges are NOT enforcing the laws these criminals are found to be guilty of.
