One of the bad things about the burqa is that a man could commit a crime. Then put on a burqa and escape. The police would think that the person was a women and knowing that the person who commited the crime was a man they would not bother to think that that person was a suspect.
I think that the burqa is oppressive to women because in most country's they don't have a choice to wear them. They should be able to express themselves like men. All people should be equal even if some people have more power then others. NO ONE should have to do/wear anything that they don't want to.
