It's looking more and more like the main motivation this guy (or guys) has is utter contempt for the police.

You bet, this guy is playing the cops like a fish, I figure as long as the game is being played this way (cops trying to be "TV detective show" heroes, media giving the shooter 23 hours per days of speculation to make him feel important, shooter changes M. O. with every new victim) its going to go on. He's proven himself way too smart for what he's been dealing with.

Get some of those California cops on the case! Remember when those two girls were kidnapped and raped, not only did the cops find the guy, they gave him proper justice, too!

Well, if this theory is correct, it explains why he picked D.C. He knew that the media would give it even more play than if it were elsewhere. He's obviously feeding off the mindless speculation on the news channels, and is using it to frustrate the police, and to keep them from developing any consistent theory on his M.O.
