I'm so behind on listening to links provided, will do that today.
In the meantime, I came across an op ed in the NYT yesterday by Charles Blow. "The whole system failed Trayvon Martin." It's beautifully, powerfully written. 1100 comments, including one by karmax, about #42, I think. He lives in Lake Worth FL. He describes a volunteer watch system they have, COPS, sponsored by the Sheriff's Dept. Volunteers have to go through a training course, and be certified. They use Sheriff's cars, with blinking lights that all the residents recognize. 2 volunteers are in the car, and they are not to leave the car nor carry weapons or flashlights. A Sheriff's Department person works with volunteers on an ongoing basis. COPS WAS at GZ HOA to present the program. Karmax said there was "testimony" GZ was present. He didn't like the restrictions and started his own community patrol-Neighborhood Watch (I guess.) And that's how he patrolled the neighborhood, armed and with flashlights, in his own vehicle.
I'm going to upload some charts later today, and add some comments, but wanted to post this right away.
