I have never had concerns about "the border" or about immigration.

19. No. No big deal .. I have live in a border city since 1985...

The majority of crime and problems are caused by US citizens.
There are the occasional travelling "gangs" that come to the US and burglarize rich folks, but most of those are middle classes looking "tourists" here for a long group package tour with visas - that go straight to work for the US based gang that recruited them.
Two months later, they're headed back to Brazil or Columbia -.or Indonesia, Slovakia, or South Africa - with a few souvenirs and a much nicer bank account than when they left "home".
But then again, there's a "open till midnight" taco, tamale, or fruits/tecolatas stand manned by the Tios within walking distance in almost every "questionable" neighborhood, and you can't throw a baseball without hitting a South or Central American food stand most everywhere else.
Again, most of the crime around here is not committed by immigrants. They're scapegoats for the punks, addicted, and crazies.
Most of them just want to keep their heads down and make use of opportunities to breathe and thrive - things they couldn't do in their home countries.
