It is about sex, hence the groping and pawing. If the attackers weren't interested in sex, the attacks would have been of another nature. The sexual aspect floats their boats, which is why they weren't knocking the scantily-clad women around with 2X4s. I'd be interested in seeing the racial breakdown of the women claiming to have been assaulted. My guess is that the majority of complainants are black and white, not Hispanic.
Hispanic women seem to take it as par for the course.
Oh, look at our naughty men with their machismo. Now, let's put on some trashy clothing, hit the clubs and suck some cock. It's only an issue when yuppie rollerbladers in Anna Sui capri pants are involved. Anyone black, white, male, female who attends an event that attracts a large crowd should plan accordingly. Large crowds tend to devolve into mobs rather quickly, particularly in the kind of sweltering heat that provokes violent acts.
