On the cop provided video, it looked like it was only two quick stabs. Then the attacker just walks away. Although the victim could have been killed by those two strikes, didn’t look like the attacker was really trying to kill him. Appeared to be more of a “pay back” incident, and not random. I suspect that some kind of interaction had already occurred between those two. If that was the case, the victim was a fool to take his eyes off that guy, for even a moment.
Expect lots more of this kind of thing in Kali, where the only people that are armed are cops, and the tiny class of “special people” who can get concealed carry permits………and of course, criminals. (Forgive me if those group descriptions overlapped a bit, and were thus “redundant.” 😉
