Quite honestly I don't understand it well enough to comment. However, when the government arrested Ted Kaczynski they listed among the bomb making materials found in his shack, sodium chloride or what they identified as NaCl, common table talt. That doesn't make me feel too comfortable.
Many people here have stuck up for the Patriot Act.
Personally I am not keen on it at all but as I am not currently living in the States I am powerless to do much about it.
All I say to people that support it is:
Would you support it if Bill Clinton was responsible for it?
