It is the perfect disguise. Unlike a ski mask, it would be poor decorum to be suspicious of someone in a burka.
Quite the contrary, in the sandbox whenever you saw someone walking around alone in public in a burka and the person wasn't escorted by a man you knew they were suspicious. They were almost always men or suicide bombers. Women knew better than to go out amongst the rapists without an escort.
