Because, how exactly does one do that?
Write my congressman; like that will do anything?
Go make a stink, get arrested, spend thousands on legal bills; and still not change anything?
Go toe to toe with them at the checkpoint, get killed; and then they use the incident as the reason for MORE "security"?
Since they're public employees, who they are should be public record. Create a popular movement that advocates shunning them/shaming them and their families in all aspects of life possible. Feel bad for spouses or kids? Too bad. In WWII the vast majority of Germans were just 'folks doing their job' and not hard-core foaming the mouth party members either. All the ones we shot were somebody's husband or son. And hell, we bombed the spouses and kids back in their hometowns too. So some ugly public interactions is getting off pretty light IMO.
Trick is getting it to that point. You'd have to work people up to be angry enough to do it, then stick with it.
Passive resistance. Crowd/clog the checkpoints so badly, it shuts down the travel completely, until the .gov folds.
There's more, but this is a public forum, and the APS TOS probably prevents discussing those ideas further anyway.
