Charles Peña in Baltimore Sun: "just as we shouldn’t sacrifice essential freedoms to fight crime—such as probable cause and the need for a search warrant—neither should we do so for the sake of security."
The reason why we and you are against terrorism is because we believe that the rule of law should be upheld and innocent people should be protected from invasive force. The purpose then of policing/security and a system to enforce justice is to adhere to such a rule of law, in which no one is exempt from such rules, regardless of whether the person is a private terrorist or a government employee.
Moral ethics and individual rights are not situational. The end never justifies the means because every means is an end in itself and whatever standard is used to justify any end also applies to each and every means. Moreover, the view that "safety" can be used to trump rights and justice invariably produces the opposite. Perhaps you should read the following book by Robert Higgs, "Neither Liberty Nor Safety: Fear, Ideology, and the Growth of Government": http://tinyurl.com/69lljx
