I remember when most instructors had a bias against anything but a 1911 in .45 ACP.
...
It's not a rare thing for a firearms instructor to be the product of their own training influences, or to fall back upon confirmation bias to validate some cherished belief. It might be because of, or in spite of, their actual training, too. People are sometimes just people.
Being a LE firearms trainer doesn't immunize an instructor from this, but not having to commercially market your training to try and capture the attention and suit the whims of the general shooting public may help insulate a LE trainer against some of the effects.
I've listened to more than a couple longtime swat firearms instructors clearly dispel stupid rumors and prejudice against some particular makes/models and caliber of guns, even if it's not something they personally/professional use and carry. I remember one week-long outside shooting school for LE I attended in the early 2000's.
One of the instructors was a swat team leader & instructor for his own agency, and an up-front 1911 guy. When he heard some snickering and joking about some S&W 3rd gens in one of the range sessions he stopped the class and put a stop to the bad mouthing. He said that while he didn't care for them himself, that in all of the classes he'd taught to other cops he'd never seen a 3rd gen S&W choke in one of his classes, and sometimes cops don't have the luxury of choosing their duty weapons. His manner was pretty damned forthright, and nobody felt like making disparaging comments about the various brands of guns present in the class afterward.
Of course, just because it's the way things work in the real world ... later that same day a couple guys from an agency who issued Glock G35's experienced multiple stoppages with their Glocks, shooting good quality factory duty ammo. The rest of the shooters graciously didn't tease them or make disparaging comments ... but neither did any of the other guns, including the 3rd gen S&W's, exhibit any functioning issues, either.
As a LE instructor you have to satisfy your admin and stay within policy, and you always have keep in mind the growing body of case law regarding LE firearms training.
Of course, sometimes the decision-making folks above you may not always see the same priorities the same way as you. "Have
we ever been sued for anything like this yet? Has any other agency around us ever been sued because they didn't do it? No? Then it's not a problem for us right now. We'll talk about it some other time. For now, let's just keep doing what we've always done. Oh yeah, the training budget's got to be reduced another 5%, too."
Another concern for LE instructors is the ever-present possibility of having to testify about your training methods in a deposition or a court case. Training files of the people you've helped train, the training unit's methods, policies and procedures, and even your own training files (including as an instructor) are going to be combed through by people looking for anything they can use against you and your agency.
Then, there's the ever-present knowledge that the people you're helping train might be forced to
use that training, staking their lives on it, maybe even as soon as when they're walking back to their cars in the parking lot to leave the training facility.
You have to remain cognizant of the things you say to your people, too. You don't want to say things that can come back to haunt you. Or hurt your agency (who suddenly decide it's to their benefit to look to take away your chair before the music winds down). If someone can look to cover or blame their own poor judgment by trying to make it look like you contributed to their bad decisions with things you said, human nature will win out.
One benefit to being a LE instructor, however, is that as long as you stay within the confines of existing law (obviously), AND teach within your agency's GO's, policies and procedures, etc, you can enjoy some degree of protection under the umbrella of your agency.
As a LE instructor you train the people using whatever guns are being issued, without deliberately undermining their confidence in what they're required to use (or have chosen to use, perhaps), whether it's by students of your agency in a class, or brought by cops from other agencies when they're students in a class you're teaching. You're teaching, not proselytizing or shilling brands of guns. Gear is gear. Training is training. You're
not a cheerleader. You're trying to help train people become able to use their gear - whatever it may be - to save lives.
Just my thoughts.
