I'm just guessing, and it's a very uneducated guess, but apparently the subjects, I mean citizens, of Baltimore, are much more dangerous than people sneaking over our physical borders.
Since the government is so suspicious of people living and working in Baltimore, I'm going to keep an eye out for anybody from Baltimore.
Even though I live in Texas, I guess the people illegally entering from the south are less of a danger than people living in Baltimore. I'm going to do my part and report anybody with Maryland plates ;-)
LOL! Not a bad idea. I spent some time in the Baltimore area when I was a kid (50s) and I thought it was a wonderful city.
I happened to be there for a conference about 5 years ago, and I was absolutely stunned. There was a thug on every corner, and straying off the main route was clearly (unless you were armed and ready, which I was not) going to be a BAD IDEA. Maybe it's improved, but then again, maybe not.
