Haha, 1 man perimeter? You can’t make this sh1t up... Did he at least have two radios?

Setting up a perimeter means you radio to dispatch where OTHER responding units should set up, not that the primary officer has to be in all places at once.

I don't know what happened here, but what I said above is how it works. Whether he set up a perimeter or not is yet to be learned.

According to reports, what happened is the armed deputy stood outside behind cover for about 4 minutes while fire alarms blared, rounds going off, people running, people dying, while he talked on the phone or radio, allegedly setting up a perimeter which also didn’t stop the suspect.

"Setting up a perimeter means you radio to dispatch where OTHER responding units should set up,..."

That must be really hard work. ;-)

Establishing a real perimeter is rather more calorie consuming but far more effective.
