Do the four snipers on top of the press boxes make anyone else nervous?

Did anyone else notice these guys? Two on top of each 'new' press box. Dressed up like snipers from a chuck norris movie. Binoculars, cameras, etc...up there, the works. Constantly checking guys in the crowd out, planes overhead. can't lie and say that didn't make me nervous today...along with the huge ALERT - no purses/bags today signs.
