But the whole idea behind the list doesn't make much sense. Supposedly, we have hundreds or even thousands of U.S. residents who are too dangerous to be allowed on a plane -- but safe enough to be trusted in all sorts of other places (subway trains, sports venues, shopping malls, skyscrapers) where someone carrying a bomb or a gun could wreak havoc.

If those on the list are truly dangerous, the government should arrest and prosecute them, with their guilt decided by courts. If they are not dangerous enough to arrest, they should have the same freedom to travel as everyone else.
