Like everyone who is talking about this everywhere...I'll Monday quarterback this too.
I've worked in the firearms industry for 20 years. In my time, I've sold thousands of Taser products to LEO/Mil/Gov/Security. I've sat in on several LEO Taser training courses. Like all LEO training, they are woefully under trained in nearly all aspects of weapon craft. Basically, most courses consist of the basic function of the Taser and how to deploy it. Everyone in the course gets to deploy a Taser on a paper target, some departments will do a "live" demonstration on a volunteer, although that doesn't happen too much any longer (I assume someone got injured being the "dummy" and then city lawyers got involved and no more "live" demonstrations). I've been the volunteer dummy a few times...being Tasered does suck, but I'd much rather be shocked then pepper sprayed....electricity turns off immediately...pepper spray does not turn off for a while.
I would be moderately surprised if that officer involved in the case had received more than 10 hours of Taser related training in her career. I'm also certain that she didn't train on her own time to practice deployment of her Taser in high tension situations...i.e. adrenaline dumps. A person is only as good as their worst training instinct. If you don't develop the muscle memory over and over again, hours per month, you are going to revert to you basic instinct...in this case, that is to draw your firearm.
I've watched the video a few times, and the thing that sticks out to me the most is that she actually yelled "Taser, Taser, Taser", just as she was trained. That leaves no doubt in my mind that she actually thought she was deploying her Taser, not her firearm. Unfortunately, her base training instinct during an adrenaline dump was to grab her firearm, not her Taser.
If I were on that jury, she would not have been convicted of anything. She didn't fail, her department training policy did. Accidents happen, and in this instance a life was lost. However...if you don't want to run the risk of getting shot by a police officer, don't try to run or dig around in your car when multiple cops are yelling commands at you.
If this had happened to a white guy, this wouldn't even go to trial. Unfortunately, she is a victim of the "woke" culture where anything a white person does to a black person is automatically racist, and the white person must have woken up that morning and said "Boy, I hope I get to shoot a black guy today...that would be just swell!"
Incompetence is not illegal...in most cases....if it were, most of Congress would be in jail. I could see the department being charged with contributory negligence for lack of training standards, and I'm sure that there will be a few wrongful death lawsuits in civil court, but I think 1st degree and 2nd degree manslaughter are a high bar to clear in this case.
