I always wonder what the motivation (I'm not saying that there is an alterior motive, its just suspicious) is when people get upset by a lack of a description. Often the description is not given because the police have a good idea who did it and do not want to spook them while the cops close in. I suspect that some people want to know what they look like so that they can be on the look out for them (those that live near the crime scene). Others I feel are looking to have some tightly held belief validated.
Nail on the head...
How many here will be honest and say they were hoping that it was an Arab?
In most sports, cold-cocking an opposing player repeatedly in the face with a series of gigantic Slovakian uppercuts would get you a multi-game suspension without pay.
In hockey, it means you have to sit in the penalty box for five minutes.
