If he was hopped up on something, a taser might not have the same effect as someone who isn’t.
If someone is coming at an officer, ready to stab him, the officer has EVERY RIGHT to kill the sh!thead.
The less thugs on the streets, the better off for us citizens.
I have no problem with the fact that they shot him dead. Heck - I think there's something to be said for the medieval practice of mounting the heads of wrongdoers on pikes outside the city walls. What I have a problem with is that the city armed them with pepper spray (which they used to zero effect) instead of taser guns as their non-lethal option.
