PATRIOT Act still alive and well

My legislative tracing experience is still impacting me every time I think about how such a huge piece of legislation was pushed through so quickly (again fear and panic...) Saw this on my weekly email from EFF:

In-Flight Confrontations can Lead to Charges Defined as Terrorism

At least 200 passengers have been convicted of felonies under the Patriot Act, often for behavior involving raised voices and profanity. Some experts say airlines are misusing the law.

Ok not the smartest things to be doing on the plane I agree, but are they terrorist?
