Man, I wish those punks would do something like that in my neighborhood. 5 or 6 guys should get together with some nice, big sticks and go patrol the streets. Let some kid throw an egg at them and then go beat the crap out of him (meaning hit him once or twice in a non-vulnerable part of the body until he cries but not cause any actual physical harm). It will only take one kid, one year. Problem solved forever.

Self defense.
