Not trying to get political.
Is / was there a "shift" in the population. I have no facts to prove this but one of the President's campaign promises any person not "totally" legal is being deported. Last summer in the Atlanta suburbs, ICE grabed a person who didn't have his paperwork, just a valid GA drivers license at a pool last summer. He was held for a couple of days and not allowed to contact his family or lawyer. Finally one of the TV stations started to ask questions and he was set free. "Just a mistake."
IMHO If I looked Hispanic or Haitian I would lay low and definitely not shop any place that advertised on station that played any form music not catering to the "gringos". A lazy ICE agent would know to go there to "fill his quota", violent or not.
