The more I think about it the more I think you are correct. Granted I have mentioned here before with a few hundred bucks I could have a gun with no serial number in a couple of hours thanks to Ghetto Gun Supply. But this Routh asshole had a rifle with a scratched off serial number, TWO ceramic plates and built himself a little sniper stand, and was there since 2AM the prior morning. This guy is a professional activist/liberal con man. With that mindset I can see him easily being under MK ultra control.
