It's like a crazy secret vigilante army!

Here's a fun story about a group of Venice citizens who patrol the streets looking for pickpockets. This appeals to me for some reason. I'll bet James will like this story too...it kind of reminds me of the red-jacketed samaritan who saved the citizens of Washington, D.C. from unwarranted stabbings.

Who was that red-jacketed man? And, did he move to Venice to raise a non-violent vigilante army? And perhaps to learn some sort of Italian martial arts?
