I'd bet good money that they are youngsters who have never been disciplined, never heard the word "no" and taught to respect property and people. You see it all the time, kids allowed to anything they like, I've seen them trashing the pub beer garden whilst the doting chavs look on approvingly. It's only a small step from that to trashing people.
