A late night visit to the perp(s)'s home by a group of "concerned citizens", followed by a blanket party, a ride out into the countryside, and being hung upside down by their ankles would be more effective. Highly illegal, and I doubt anyone in today's society has the 'nads to do it, but it would be very effective.

People lack the guts to do stuff like this because they’ve become accustomed to the idea of always relying on someone else to do their dirty work. Instead of beating the miscreants black and blue, they prefer to retreat behind being ‘civilized.’
