The prison here is a GEO prison now as well. I just remember when I was in D.C. the security guards there were less than impressive and then a couple years later they had the nut job go in there shooting.
I only know one security guard, not at a prision though, anymore, not 100% sure if he's armed, I think he is. All I know is he had to move back in with his parents because the pay was to low to meet his obligations for his kids AND pay for a place to live.
