"In the current climate of terrorism from Islamic extremists and heightened security, I think it is justified to ban the use of such garments which disguises the wearer."

Yes, which is why this ban also covers sunglasses, baseball caps, balaclavas, and motorcycle helmets.  Oh wait, no it doesn't... just the niqab for some strange reason.

You can say "terrorism", "security", and "disguise" all together in the same paragraph as though you're making a sound argument, but that doesn't mean you are.  I don't like Islamic terrorism any more than you do, but please point out a single Islamic terrorist who used a burqa while conducting a terror attack.  Usually, they don't bother... they shoot up the place or whatever undisguised.  They don't care about hiding their identity... they *want* people to know who they are!
