Part of the problem though too Len, as you know, when people have shit like that happen to them, and then they "get their record sealed" people will blow smoke up their ass about what that actually means, which causes a mindset of "I can forget about it because so and so said because sealed this never happened" etc. Hell I know a woman who is a prohibited person (a federal conviction, no less!) that someone told her after X years she could get her rights back, she was kind of dumbfounded when I told her that wasn't possible under the current system unless Trump or whoever gives her a pardon...
I also wouldn't put it past a bad LEO, DA or ADA/prosecutor actually telling people lies about this stuff to get them to suck for a plea on something, either. There's no penalty to the system for blowing smoke up the ass of the accused. Unless the judge broaches the issue
at some point, they'll never know until later...
