Can you explain to me why the police need to wear black ski masks when they make these raids? Why don't the officers making traffic stops wear them?
I would presume to protect their faces from flash burns, a clawing suspects' fingernails, or other hazards. That's just a guess. I don't know their policies and procedures.

Perhaps there is no reason to.

The reason I've read on several Cop websites is they wear them to prevent burns in case of an explosion or fire. Of course there's also the ego factor of looking really frightening.
