This has all the markings of a very strange story: Rev. Lennox Yearwood Arrested at Petraeus Hearing.
I hope we get to hear more about what exactly happened; certainly the first, perhaps one-sided, report is disturbing; on the other hand, the video is less clear-cut — after being singled out for some reason and denied admission after waiting in line (could it really be for wearing a button that said “I love the people of Iraq?”) did Rev. Yearwood really lunge for the door saying “I will not be arrested”? And even so, does that justify breaking his leg?
Rev. Yearwood is the same person who recently won a stay or delay in his case against the Air Force which had tried to honorably (not dishonorably) discharge him as a chaplain; according to his supporters, his offense was preaching against the war. And indeed, when he got an opportunity to preach at Andrews Air Force Base, “the message that I preached was 'Who Would Jesus Bomb?'”—not the best way to be popular on the base, I'd imagine.
I spent some time trying to find out if there's a Senate rule about what you can wear to a committee hearing, and whether buttons are prohibited. Couldn't find anything. Links to facts most welcomed.
