Vandals Damage Classic Car Fleet

Item: Vandals have ball with 26 classic cars: Owner observes two men smashing windows of vehicles /David Cole, Coeur d’Alene Press

More Info: Donald R. Martin said he wants the culprits castrated. It all started about 5 p.m. Thursday when Martin was sitting inside his home at 5414 N. Huetter Road and heard what he thought were gunshots being fired in his wooded backyard. Martin left his home to see exactly what was happening and saw two young men smashing the windows of his fleet of classic cars. It looked to him like they were using a metal rod.

Question: What would be a fitting punishment for these two punks?
