Sorry, I think the "burqa bomb" argument is silly.
I could just as easily hide a body bomb under my bulky down winter coat, my heavy leather bomber jacket, or my lightweight, loose fitting, nylon summer windbreaker.
It's rained up here the past 7 days and I've gone out every day with my Scotchguarded windbreaker loaded with the stuff in the picture below.
(I threw in the Freerepublic.com Pajama Patrol Deputy Badge just for grins. I only bring it along for "show and tell" at Freeps or Townhall meetings)
As you can see, there's more than enough bulk for a plastic explosive bomb (I don't think terrorists use dynamite much anymore). Plastic explosive could also be easily molded into the shape of a beer belly, and I wouldn't even need the windbreaker.
The load in my windbreaker doesn't even take into account my computer bag. If I'd brought that along, and it was loaded with C4, I could probably take down a small building.
Once when my shoulder was bothering me, I got on the scale all decked out for work. Fully loaded, with my computer bag, I was humping 35 lbs (no wonder my shoulder hurt). 35 lbs of plastic explosive could make a big boom.
Nobody stopped me, or even looked at me askance. A potential human bomb, clad entirely in Western garb.
Just two weeks ago, Joel Hinrichs III "blowed hisself up real guud", and he wasn't wearing a burqa.
So, the argument for banning burqas because they could hide a bomb, is, sorry to be frank, stupid. Face it, Westerners hate burqas because:
a) They're denigrating to women.
b) They're indicative of muslim's refusal to integrate into the Western society to which they've chosen to immigrate. ("I'm in your face" and "We're going to take over your country").
c) They expose muslim men's culturally enhanced sexual insecurities.
d) They're just plain Medieval, scary, and ugly.
I still contend that burqas can be used to our advantage. The retrograde women who wear them are saying "Look at Me! Besides being an idiot, I have a husband who wants to kill Westerners, Jews, and Christians! I think you should follow me around and find out who I associate with."
