The U.S. government has lowered the threshold for information deemed important enough to put suspicious individuals on a watch list or no-fly list, or have their visa revoked, as a result of the failed Christmas Day attack, senior State Department officials tell CNN. For example, citizens could be put on the no-fly list or a watch list based on one credible source, instead of the previous standard of using several sources.  If this applies to US citizens - we're not sure yet if it does or doesn't - then if you don't like your neighbor, just make a quick call and report something suspicious!  Somehow, this reminds me creepily of Stalin, the Shah, and Pinochet...  As Ben Franklin said, "Any society that would give up a little liberty to gain a little security will deserve neither and lose both."
