In short, not so patriotic after all.
In the aftermath of 9/11, the Patriot Act was passed. This bill, introduced on October 23rd 2001 and signed into law just three days later on October 6th, allowed for the violation of many Constitutional rights in the name of increased security. Among the many controversial aspects of the bill is Title II, which grants the government the ability to conduct surveillance on individuals without a warrant and for the information collected to be valid evidence ("Surveillance" being loosely described as the ability for the government "to intercept wire, oral, and electronic communications" relating to terrorism, computer fraud, and abuse offenses.) Without a warrant.
This is not only an infringement of the 4th amendment, but also a direct threat to American freedom. Security of information and communication is a necessary element of a democracy, and the seizure of these rights is characteristic of a repressive dictatorship, not a thriving democracy.
