"in reality, things like this almost never happen" I am willing to bet your life experience is very different than those of minorities.
" If the guy had pulled out a gun and shot the cops in the head, we wouldn't have heard a thing about it" Not sure what you base this on, I feel like to could be based on nothing but the narrative you are attempting spin. Is your argument that police should be more aggressive based on what could happen? Should police just gun everyone down because they may have a gun and pull it out and shoot them in the head?
In this country, police have godlike life or death power, every instance of police killings should be heavily scrutinized by neutral parties and stringent protocols put in place to prevent it with harsh criminal penalties for those that dont follow the rules. How you can just shrug and accept any cases of police brutality is beyond me.
Cops are humans. It is illogical to assume that there will be no mistakes made.
"Cops are humans. It is illogical to assume that there will be no mistakes made." They are but when they make mistakes people die or are sent to jail for decades or are stripped of their property. To give people this much power and shrug and say its a mistake is not acceptable. Very often these same cops have many / dozens of complaints against them and they still continue to act with impunity because they know that they are not going to be punished. A mistake is a mistake, 10 / 15 mistakes in and it is a pattern, extrapolated out over tens of thousands of officers and it is a systematic problem.
In reality USA has 3-10x the number of police shootings per capita than a random western country (heck, worse than many developing countries of even dictatorships).
So, yeah, the metrics are off.
If your counter-argument is "yeah, but US has more crime too", then maybe think long and hard if your whole legal system, approach to crime, society goals, etc, are justified then....
