Weighing in on immigration

Rico says his friend Rich Shaner sends along this splendid little (apparently) true internet story:

I have a friend who is president of his homeowners association in the Dallas, Texas suburbs, where they were having a terrible problem with litter near some of his association's homes. The reason, according to my friend, is that six very large, luxurious new houses are being built right next to their community, and the trash was coming from the Mexican laborers working at the construction sites. It included bags from McDonald's, Burger King, and 7-11, plus coffee cups, napkins, cigarette butts, Coke cans, empty bottles, etc. He went to see the site supervisor and even the general contractor, politely urging them to get their workers not to litter the neighborhood, to no avail. He called the city, county, and police and got no help there either.
So here's what his community did: they organized about twenty folks, named themselves the Inner Neighborhood Services group, and arranged to go out at lunch time and "police" the trash themselves.
It is what they did while picking up the trash that is so hilarious. They bought navy blue baseball caps and had the initials INS embroidered in gold on the caps. It doesn't take a rocket scientist to understand what they hoped people might mistakenly think the letters really stood for.
After the Inner Neighborhood Services group's first lunchtime pickup detail, with all of them wearing their caps and some carrying cameras, 46 out of 68 construction workers did not show up for work the next morning, and haven't come back yet. It has been ten days now.
The general contractor, I'm told, is madder than hell, but can't say anything publicly because he could be busted for hiring illegal aliens. My friend and his bunch can't be accused of impersonating federal personnel, because they have the official name of the group recorded in their homeowner association minutes, along with a notation about the vote to approve formation of the new subcommittee. Besides, they informed the INS in advance of their plans, and according to my friend, the INS said, basically, "Have at it!"
