Lashes with a whip will be letting them off easy...the hand(s) they used to do the damage should be cut off in public. If they come back and use another appendage, like their feet, it should also be removed in the same fashion. I would like to see them comeback in a wheel chair and try to throw or swing something with their lips. This will deter others from like behavior. I am not a violent man, but society and parents for the most part just don't care about the property of others. I also have wireless cameras around my house and property, and inside of my garage. I also place a "Hot Seat" on the drivers seat when the car is in the garage or in public for a long period of time. "Hot Seats" were big in the mid 80's...it looks like an ordinary seat cushion, but is filled with razor blades, barb wire, an 1/2 inch tacks the cushion has a hard bottom as to not damage the seat when performing its duty.
