One of our founding children had a few comments about that trade off.
We survived the Japanese interment camps, we survived many activities that most of us would rather never have happen. Another VERY great founding father once said....(we leave to you) a republic, if you can keep it.
For some of us keeping 'it' means taking steps towards prevention of terrorism, for others, like yourself, it means bending over backwards to be politically correct, avoiding making the boo boo of withholding specific freedoms to individuals who fall into the category potential threats. Tough.
None of us will have any freedom at all if it comes to living in fear all the time. That is MORE than worth an ounce of prevention, imho.
