Safety at what cost? (Part 1)

Since the September 11th World Trade Center attacks, the safety of Americans has been the priority of this administration. This goal seems to outweigh all other considerations. Thus, we have:

• the abuse of prisoners at Abu Ghraib in an attempt to extract information to safeguard Americans
• people detained indefinitely at Guantanamo without any recourse or any rights except for those guaranteed by the Geneva Convention
• wiretapping of people's cellphones, landlines, and emails
• a TSA that arbitrarily changes its rules on prohibited items
• a list of suspected terrorists without procedures for removing people listed wrongly (of course, the government doesn't make mistakes)
• a war in Iraq because Iraq was harboring weapons of mass destruction and sheltering terrorists; we still have not found any weapons of mass destruction and the terrorists that we're fighting are a result of the country's invasion
• student visas to the US are routinely delayed or denied
  

At what cost is this policy of protecting Americans from terrorists? Are we endangering the values and the freedoms that made our country great?
