Our world may be dangerous, but we Americans are submitting to this fear. I point out the Fourth Amendment freedoms that were withdrawn with the passage of the Patriot Act as an example.
We now know, because of Edward Snowden, that the government has been collecting meta-data phone records since the passage of the act in 2003 without our authorization, and some of us are cool with that.
The whistleblower is still in Russia. He did the right thing, and our officials blame him. Fortunately, there is the prospect that this egregious part of the Patriot Act will end because of inaction by Congress. If you like that outcome, you might want to contact your representatives.
