Before I start I just feel the need to highlight, you have me and So Boerd on the same side arguing the same point here.
When you have that happening that should honestly say something.

[quote=Rare]I did read that and I'm just sharing my thoughts on this topic. Yeah, he would still feel away if his father's death was preventable, but that's life.[/quote]

Life sometimes may not be fair, but that doesn't mean an innocent person should die out of fear for their aggressor's safety.
Life isn't perfect, but that's even more reason for us to rationalize these things and try to get the best realistic result possible, rather than making good people die and making life a bit worse as a result.

[quote=Rare]Okay, he wouldn't die due to the stab wound, unless it damaged the organs and they didn't make it to the ER room in time.[/quote]

Or bleeding out, no matter where you're stabbed if enough blood escapes you're as good as dead. On top of that, if the boy was charging him with a knife it is safe to assume the boy intended to aim for vitals.

[quote=Rare]Okay, where did you get that I said, "Let the officer just lay on the ground and die.". No, I didn't say that, I said that he should fight him or use his taser on him.[/quote]

Brovo already brought up the Tasers, and when shown why that wasn't practical to expect he was able to look at the evidence, accept it and retract his previous suggestion/criticism.

As for fighting without a Gun or Taser? The boy has a knife, the officer has his fist or a night stick. Doing so put the officer in far greater danger than need be, and what if say he failed and the boy did kill him? Would other officers be expected to shoot or would they also have to risk their lives is close combat?

[quote=Rare]Go to other countries, that don't allowed guns in the police force, and tell them that.[/quote]

No country completely prevents police from using guns. Some countries simply require it to be a higher level of law enforcement first.

For example in America practically everyone has a gun, in Canada it's common but wouldn't be present for all cases. In the UK they'd probably have to specifically call in for armed support. But an armed boy robbing a store and attacking people? Even in places like that UK that's pretty good grounds to bring in law enforcement that's armed.

[quote=Rare]Well, I would just shot him in the arm or the leg. Making him drop the knife and the old lady lives another day to shop.[/quote]

This was also already addressed, and explained how aiming so precisely (with a moving target no less) is not only risky and difficult, but chances a misfire where someone else can get hurt.

[quote=mdk]No amount of logic is going to affect a change here. Just be done. Internet argument cool-rules aside, at some point, you have to be able to look at another person and reasonably conclude that they've got their head up their ass.[/quote]

True, but a decent attempt should at least be provided before deciding to give up on such a thing.
