One of the July 21st terrorist suspects escaped wearing a burka.
The burka has been used as a disguise by thieves.
It's a great all-round disguise. It makes people think you're a woman, and therefore less likely to be a violent criminal. It shows people that you're a Muslim, and therefore challenging you is "racist".
Normally anyone who wandered round wearing a piece of clothing that entirely covered their body would be stopped and searched by the police. But if you're wearing a burka, this doesn't happen. Because if a Muslim woman wearing a burka was stopped, the human rights/Islamophobia lynch mob would be on the case within hours, and there would be endless recriminations. So you can walk absolutely anywhere wearing one.
The burka is a criminal's wet dream. An absolute disguise, and virtually no chance of being stopped. It also symbolises oppression, and a backward, barbarian culture that is spreading like cancer. Let's ban it now!
