I'll take the TSA patting me down before every flight compared to the alternative . Look at the number of guns they take away as it is. It's in the hundreds.  Due to an aircraft's air pressure system guns are the last things we need on board. I'm not pro union---I just want to see us be able to travel safely .  In most cases less government is the way to go.  We have never seen such dangerous times . The only thing between safe flights and constant aircraft hijackings and downed airplanes is the TSA .  Who else is going to keep us safe ?   If carry on's were disallowed  there would be no lines at check points.   If your getting randomly selected a lot , you might look in the mirror and ask yourself how your presenting yourself .  Police and customs inspectors over time develop a sixth sense of sorts of being able to tell who needs closer checking. Maybe your giving off that vibe .  We all should be proud of TSA for their efforts to keep us safe . They clearly deserve our respect .
