This is why we have to fight every single encroachment on our civil liberties - they invariably get used for other purposes, simply because they can:
Reporting from Los Angeles and Oklahoma City -- Tamera Jo Freeman was on a Frontier Airlines flight to Denver in 2007 when her two children began to quarrel over the window shade and then spilled a Bloody Mary into her lap.
She spanked each of them on the thigh with three swats. It was a small incident, but one that in the heightened anxiety after the Sept. 11 terrorist attacks would eventually have enormous ramifications for Freeman and her children.
A flight attendant confronted Freeman, who responded by hurling a few profanities and throwing what remained of a can of tomato juice on the floor.
The incident aboard the Frontier flight ultimately led to Freeman's arrest and conviction for a federal felony defined as an act of terrorism under the Patriot Act, the controversial federal law enacted after the 2001 attacks in New York and Washington.
"I had no idea I was breaking the law," said Freeman, 40, who spent three months in jail before pleading guilty.
Freeman is one of at least 200 people on flights who have been convicted under the amended law. In most of the cases, there was no evidence that the passengers had attempted to hijack the airplane or physically attack any of the flight crew. Many have simply involved raised voices, foul language and drunken behavior.
Some security experts say the use of the law by airlines and their employees has run amok, criminalizing incidents that did not start out as a threat to public safety, much less an act of terrorism.
In one case, a couple was arrested after an argument with a flight attendant, who claimed the couple was engaged in "overt sexual activity" -- an FBI affidavit said the two were "embracing, kissing and acting in a manner that made other passengers uncomfortable."
