Yes , Security guys are very antsey, they know at some point some whacko is going to come sailing at a dead run right down to their principle whom they are guarding, and on top of that,many of them are so pro BO Tox , that they are letting their anger show.
Personally I would not want to be at the front of any room where these guys are, and very near a well marked, wide exit.
Fer sure .. and they know it’s gonna get worse.
They may have to put themselves in witness
boxes ... apart from the crowd .. LOL.
