A few weeks ago I noticed an armed private security guard outside the new Bank of America tower on 42nd Street; today there were two, both sporting Wackenhut logos on their shoulders. These aren’t some paramilitary Hercules team sporting machine guns, they’re just guys with sidearms patrolling the sidewalk in front of a bank. Which might be normal in Charlotte, I don’t know, but is certainly not something I ever remember seeing in NYC. Any idea what purpose these guys are meant to be serving? And are they going to be there permanently?
