Whenever you see something such as this, on either side of the argument, and among any ethnic group, and regarding any "hate" crime, the first thing you should consider is the possibility that it was self-inflicted to gain sympathy for the victims' cause. It is akin to Munchaussen(sp) Syndrome wherein a person injures themselves and makes it look like their enemy did it, so they can reap the rewards of sympathy from others. Consider this each and every time you read about a "hate crime," especially those in which no one is injured. It happens more often than you know.
