My one and only experience with an incident similar to the OP's was with a car load of teenagers, and one armed with an AirSoft. My instinct was not to catch the perps to do a major beat down, but to make a quick getaway when the carload circled around for a second shot.

My gratify moment came a few months later, when I read in the local paper, that a teen had been arrested for shooting a pellet gun at his neighbor's house that was only a few blocks from where my incident took place.
