I’m assuming we’re talking about Florida here… that said up until 5-10 years ago (and in some cases more recently) most LEO training was “hold position and wait for SWAT”. The deputy had been a cop for 30 years. So for at least 2/3 of his career the predominate thought was you don’t enter without bigger guns/backup. Creatures of habit we are, and add some (reasonable) fear it can cause hesitation that can cost lives.
I went thru active shooter training in early 2015 at Glynco(Fletc) as part of a basic LE academy. I’ve been working as a fed LEO since then. They treat active shooter training like a science but the only thing in common with these scenarios is nothing is ever the same. I’m curious how good the training was/is on a state level, especially for follow on training. I did like 80 hours of entry and respond type training including simunitions, blank firing, actors present. As an individual, with partner, with partnered… etc. I always thought this is all well and good but no amount of training can make up for just being lucky- you enter a building and guy kills himself, or you are right behind him and can issue a coup de grace quickly, or 5 other LEOs are down the street having pre-shift coffee and get there as you’re pulling your patrol rifle out of the trunk.
Until one is in the actual shit they don’t know how they’ll respond; four minutes is both a very long time and a very short time.
I was on a ship that had a man overboard in very bad wx conditions- 8 foot seas, 40 knot winds, dark, cold. The coxain of the “rescue boat” did not hesitate to get in and go. The other guy who was supposed to get in the rescue boat was nowhere to be found. Fortunately, the welder, jumped in and did his non-assigned duty. He was in shorts and a t shirt. The saved the dude but the guy who should’ve gone in his stead froze up. Happens.
That’s why it’s generally luck that wins over skill in a lot of these situations.
