I'll ignore for the moment the fact that he wasn't even breaking any laws. But let's suppose he was. Isn't the point of civil disobedience to provoke a reaction, and get yourself hassled over something that shouldn't be illegal?
So yes, let's suppose he did ask for it. Let's suppose he did want his 15 minutes of fame on the blog or -- dare he hope? -- the local news. That doesn't make hassling him okay. Instead, it proves he was right.
I don't feel sympathy for him, nor would I expect you to, so you don't need to point out again how little you feel. He was trying to make a point about the brain-dead, incremental encroachment on our liberties. Everyone who took offense at what he wrote helped him make his point.
Don't tell me he asked for it. He did. Don't tell me it was his own fault. It was. Try, if you can, to not address his tactics again, and instead address his point. Any criticism you care to make about his tactics, I will concede in advance. Now, what should happen to the screener who pulled him aside, and the supervisor who didn't immediately pass him through? What changes should be made in the rules, or in the training of those who enforce them, to make sure this doesn't happen again?
