At the time of writing this comment, this youtube video
https://www.youtube.com/watch?v=xDhtUpGdn_0 came out less than 23 hours ago about how police should use as little force as possible when apprehending suspects, not as much justifiable force as possible.
I watched the whole thing (it's 28 to 30 minutes long), and if any of you don't feel like watching the whole thing, then just at least watch the first 11 minutes of it, since that is where they talk about the most important stuff, and the most important things it talks about are the difference between justifiable force and necessary force, as well as how police can sometimes be too quick to rely on their weapons (handgun, taser, baton, pepper spray, etc) instead of using other means to apprehend suspects without causing any harm to them, such as talking a person down, and using grappling holds to effectively restrain someone without harming them.
Justifiable force, in this case, would be the amount of force a police officer can legally get away with using, so if I am a police officer, and I am tasked with apprehending a dangerous suspect that raises their fists and start punching me to death, I would be "justified" in killing them with my gun immediately. However, depending on the suspect's size, speed, and strength, it may not be necessary to kill them immediately, and instead I could try to disarm him, take them down, and restrain them safely without getting them or myself hurt.
This is what happened back in 2014, and this was also discussed in that video, 15 minutes into said video, where an officer was trying to apprehend a dangerous suspect after the suspect attacked someone else, the suspect got into a fight with the officer, the officer ended up on the ground, with the suspect on top of him, beating him to death, and the officer drew his gun and shot him twice, killing him. There's an article about it here:

The youtube video then goes on to suggest that the police officers use different grappling holds to keep the suspect under control without harming them, instead of being so quick to use deadly force, and that police officers should be trained to use these effective grappling holds more often. Maybe George Floyd would still be alive today if his killers held him down this way instead of choking him with their feet.
