I get the overall point you're trying to make, but for the person who was going to be that #5 shooting and gets to live instead, that's a positive outcome for that person at least.
Overall there's certainly a larger discussion about the use of force, and maybe tasers contribute to that in some negative ways, but most of the time they're used everybody gets to live at the end of the day.
You shoot 200 people with tasers, a few are going to die.
You get 200 people fired from their jobs and make it hard for them to get employment elsewhere, a few are going to kill themselves. (Or see if they can get revenge first.)
Go look up real numbers. Amount of unarmed black men shot year by year and up-to the riots. Look it up. And you're right the number is historic...ly low under Trump and was literally spiraling down to Zero before the riots, you could count the on your fingers and have one to spare.
In theory, tasers are good because they can substitute shooting.
In practice, you had 5 shootings, and now you have 4 shootings and 200 taser uses
