Some radio commentators put it very well: They just keep chipping away at our liberty and privacy a little at a time and we don't complain because is just a little. Of course, eventually, all of our liberty and privacy will be gone.
The U.S. gladly spends the lives of soldiers to protect out liberty and our way of life. So, why then are willing to give up that liberty and way of life just to prevent terrorists from getting onto airplanes? The Israeli model seems the better approach.
BTW: Seeing how they are chipping away at our liberty bit by bit, I now understand why the NRA fights gun control at every single engagement and treats every engagement as if it were the most important one ever. It is to prevent the chipping away. I had been considering dropping my membership. However, I think I will now renew for another year.
