Methinks there is some paranoia out there. The reality is, given a base rate of 0.0073% (yes 73 ten-thousandths of a percent), for being a murder victim we are actually quite safe here in America.
According to the LEOKA (law enforcement officers killed or injured in action) data there are 1.5 officers who lose their life by their own hand for every 1 officer that dies due to hostile action. Or, any given officer is 50% more likely to take their own life than die by hostile action. Or, for the officers at that table, if two are shot and killed by a booger-eater, three will take their own life.
I suspect the 6 (or 8) officers, with mutual coverage and interlocking fields of fire, are going to be okay at the local Pizza Hut.
