I can't help but feel that arresting him was a mistake. And I shall explain...

Your man Kazuo, by his own admission, got his rocks off at the notion of people being shocked by his antics. If the entire community, police and all, shrugged their shoulders and said "Meh - Dirty Kazuo is up to his old pants tricks again." then that would cool his ardour.

The only way that cast-iron plan could backfire would be if he then went on to new heights of shocking.

People might be upset if he started scattering the girls liberally around his neighbourhood.

Either with or without the pants.

I think this is one of the funniest criminals ever. I wish I would have thought up of a prank that funny. Imagine walking outside and see a whole bunch of womens underwear everywhere.
