I watched a special recently on the rise of mexican gangs in California over the last several years. I can't remember what channel it was on. If anyone can find info and link it, my internet load time is killing me this morning. Like many of the bottom-income groups, once they fill all the jobs (which I am fine with them taking because I won't), many turn to crime. There is a spot in Chicago I used to pass where illegals could be picked up daily for jobs. The lot was usually full half the day. Employers would pick them up by the truckload till they had enough people and the rest would walk off in to the neighborhoods once they knew there was no more work. These pop up around the city and change areas when the police start cracking down.
