One thing I have to hand it to Twitter for is that they wrote an explicit carve out for their "no glorifying violence" rules to militaries and governments.
This seems to be somewhat implicit in our society ("violence is bad, unless it's our heroes doing it to people another color far away, then woohoo bombs away!") but usually unsaid and unexamined. It's a good moral move by Twitter to point out the contradiction.
A better move would have been for them to simply ban everyone calling for violence, militaries included (if and only if they are going to be banning people selectively based on content, which they are, which I think is bad).
Does this include "We killed Osama Bin Laden" [perhaps with some details and photos of the operation]?
