IMO, the real threat is not the drywall worker
returning from a Mexican family visit - it's
misguided Islamists that are new Wetbacks..
The politican who uses his freedom of speech to
explain that - gets my $$.
That is a real concern. I am not comfortable with the cartel connected armed smuggler or human trafficker of teen girls either which is mostly what passes through here.
Most who have a decent job (your example of drywall worker) here or even family that are doing halfway decent are not the ones hiking across the desert now though. Most of them drive across the border through legal crossings and claim to be coming to visit relatives or shop, then just stay.
Years ago it was mostly workers passing through the desert but now it is mostly hard core criminals of one variety or another. At least that is what we are seeing here. I can't even remember the last time I came across an illegal out here that looked like a worker or even asked about work.
