Locking Down the Capitol

This news, Cyclist Killed By Military Vehicle, puts the pictures in a whole other light.
All of Matt Y.’s post is worth a read. He sums it up with:

I think there are perhaps some lessons here for the question of the prospects of actually conducting military operations that protect civilian life. The fact that people conducting a security operation on American soil can’t even react to accidentally killing an old lady by saying “we’re sorry we killed that woman” rather than lets “make sure the pedestrian didn’t run into the truck as it was moving” doesn’t inspire a ton of confidence.

I don’t think DC has national guard troops to call on for extra manpower. IIRC, the DCPD, Capitol Police, Secret Service, and Pentagon (and others) were all involved in the security arrangements. They did a pretty good job overall.
