No I'm not saying cops should be unarmed but changes are coming one way or another. It's true the justice system does not bring back dead officers but we must face the reality that officers are going to get killed in the line of duty. What we cannot ever accept is innocent people being killed because the officer felt threatened or the suspect was uncooperative.
If the officers life or the life of others are not in immediate peril then lethal force is not justified under any circumstance.
Not following commands, being uncooperative, holding an unidentified object, running away and on and on and on does not meet the criteria for lethal force.
I think you are on track with crappy training. This is where I am on this subject as well. In my opinion it's not exactly crappy training but more along the lines of negligent training. It appears that officers are literally being trained in such a way that it almost guarantees they will end up shooting when they shouldn't. How else do you explain shooting unarmed women through windows, Shooting people when an officer goes in the wrong apartment, people who are clearly fleeing and even in this case where the man was surely disobeying commands and was uncooperative but did not have the officers or others lives in immediate peril.
Unless there is something we are not being told about this shooting it was without a doubt a bad shoot and lethal force was not justified. The suspect was uncooperative and was being detained so at that point the job of the three officers was to affect an arrest using whatever non lethal tools and techniques were available to them but lethal force was not an option.
As soon as he leaned in the car, I’d say the cops were green-lighted. Looking at the video, I would think that they would anticipate that was where he was going, and knowing that if he got in they were going to shoot, it became incumbent upon them to see that he did not open the door. They may not have known it was his car, whether another person in the car might be armed.. any number of factors.
No-knock raids, spawned by the War on Drugs, are another problem. Warrants served on the wrong address...whether the cops do it, or a clerk types it incorrectly...all of these things can snowball into tragedy. Shooting a woman through a window is inexplicable, as was the rookie Somali cop shooting the Australian woman in Minneapolis.
I can justify the use of lethal force if the three LEO unsuccessfully attempted to affect the arrest perp broke loose and reached into the car. But from what I saw in the video, LEO never attempted to use non-lethal force, such as the use of a taser or pepper spray or even tackling him to the ground. LEO never should have let the perp even approach the car door.
