I just don't understand.......

I am not trash talking any officer's/deputies either. I have lots of friends and family that are in some sort of law enforcement. But there are tons and tons of videos online where i think to myself , "is this a bad / dangerous situation? " yep. "Did this person deserve to die? " hell no. I totally support the law and the folks enforcing it. God knows without them this would be a hell of a bad place to live. But i think there should be alot stricter restrictions as to when "deadly force" can be used. Like it was stated above. Deploy the taser first. And until the subject is endangering yours or someone elses life i simply dont think the use of deadly force can be justified. Now if someone "rushes" you and gets pretty dang close with the weapon then maybe its time to shoot. But i would have to take some leg shots first. I know alot of places teach that if the trigger is pulled its center mass or shoot to kill and all that. But i dont think it should be that way. Just as an example... if a fella rushes me with a screw driver in his hand , and ive already got a 40 caliber hand gun pointed in his direction i would be willing to bet a years pay that i would be able to take his legs out before he was able to get to me. Simple as that. Now you would have to be able to think clear enough to be able to know when the subject was to close and then comes the kill shots. I cant help but think about peoples families and things like that. I've never been in a situation like that and i pray that i never am. Even though i know for a fact i could take a life if i had to. It would ABSOLUTELY have to be the end of the line, last straw , bottom line , me or you type of situation. I'll shoot for the legs and maybe a gut shot and hope the medics can save your life when they get there, before i try to kill ya. Now a person with a gun is a totally different ball game. If the gun ever gets pointed in the wrong direction.... its over with. I didn't mean to ramble and go off track but i think sometimes people die for no reason.
