there are a lot of weirdos at the gun shows, they are like the flea markets of gun sellers. That seems like it is the same everywhere. I bet nowadays with so many first timers that they are even worse. On the other hand people are almost never shot at gun shows, that's one of the safest places on Earth!
I am in MA where we also have racist cops who decide who can exercise their basic human rights. Most gun laws are designed to keep the poor and/or minorities from carrying legally.
