Who the hell do they think they are?

It's 5pm, broad daylight, and 3 boys who are like 10 or 12 decided to attack me for my purse. What is wrong with them??? I called the cops which demonstrates some modicum of adulthood, however considering they appear to live in the building next door, I doubt our next encounter will end as benignly with a police officer taking statements. I think some edumacation is in order.
