A guy with a knife acts aggressively towards man with gun.  Stupid guy with knife gets shot.  It works out whether it's a cop or one of us with the gun.
There are a lot more violent people out there acting stupid these days.  People bitch about cops not doing anything but then when they do, which means putting themselves more in harms way by interacting with these people, it's going to result in more shootings.  Not becaus the cops are more likely to shoot, but because they are in more positions where they will need to.  If they only interact with 20 criminals a year they will have less shootings than when they interact with 100 per year.  Common sense here.  If you want to reduce the number of dumbasses with knives getting shot, then stop whining when cops spend most of their shift at Starbucks and the donut shop.
If you think all these people are so nice and can be talked into dropping their weapons you need to get out more.  Leave your nice little neighborhoods and actually spend some time around some of people in the ghettos.  I've lived in the "projects" in a small city in California, I've been in the shitty parts of DC, VA, MD, Seattle, Tacoma, Fed Way, etc.  No difference in the "hoodrats," that term that people here like to throw around when talking about the criminal scum in some areas... oh except when it's a cop shooting one of them apparently. I live in what many people consider the ghetto right now.   I wouldn't have cared if the guy trying to argue with the cops on my front porch would have been tased last month.  He kept trying to argue, wouldn't take his hands out of his pockets, kept yelling at the cops and acting the fool.  He went away in handcuffs, while his buddy who was calm, quiet and not being a knucklehead was told he would leave 5 minutes earlier.  See how that works by the way?  Two people of the same color, stopped by the same cops.  One walks away, the other in handcuffs after almost being tased.  What was the difference?   Same thing for two people with knives.  One puts the knife down when told, the other doesn't.  Yet it somehow isn't reasonable to shoot the guy who not only doesn't put the knife down, but actually moves towards the cop????

And you accuse me of making up shit and not reading everything you wrote.

Read the first part again.  The more cops interact with people, the more criminals they actually deal with the more shootings will happen.  It's pure numbers.  Even if the percentages are exactly the same in Tacoma, Bellingham, Yelm, or Moses Lake, there will be more shootings in Tacoma because there are more people and more interaction.

The more interaction with criminals the more necessary shootings will occur.  And actually, yes there will be more mistakes.  The more you do something, the more you do it right, but it also does mean that more mistakes will happen.  But then again, I don't feel shooting a person threatening you with a knife is a mistake.
Since you are such a know it all why don't you become a cop and show them all how it's supposed to be?  You're so fucking full of yourself it's sickening.
