Neighborhood watch groups are coming under some scrutiny after a volunteer watchman in Florida shot and killed an unarmed teen last month.

The death of 17-year-old Trayvon Martin has some neighborhood organizations taking a closer look at their operations. In the Stratfield neighborhood of Fairfield, neighborhood watch members don't actively go out on patrol, they keep an eye out from their own homes. The group is overseen by the Fairfield Police Department, which says it screens applicants and puts them through a five-week training program.Bridgeport churchgoers voice outrage over Trayvon MartinBridgeport youths plan anti-violence march for Trayvon Martin
