IMO, that's not a 'large knife'; both blades are under 3" long, and Oregon has some of the most lenient knife laws in the country, which makes that knife quite legal to possess and carry. Surely, pulling it on a police officer represents poor judgement, but probably isn't something he deserved to be killed for.
"We have guns, ballistic vests that protect us from being shot or stabbed, years of training in how to use those guns and how to defend ourselves and take down a bad-guy, yet any sorry sonofabitch with half a threat must be gunned down."
Try actually policing this town, you jackbooted thugs.
