How large is the group of people who think it isn't wasted effort?
I recently had a conversation with a group of well-traveled, well-educated people who honestly believed that the new scanners and pat-downs are okay because they are designed for our own safety. The 4th Amendment was never a concern to them. When I brought it up, the answer was essentially that the end justified the means. Ben Franklin's famous words[1] did not convince them otherwise.
How are you (general) educating people about their rights?
