I can't tell for sure, is that a white guy or a future saint that charged him with a hammer?

Potentially neither. Off white? It was a hatchet, and the hatchet man's name is Edward Samaan.

Not that it matters, as I think this was mental illness/suicide primarily. It wasn't necessarily or even probably motivated by anti-police attitudes. I think the dude just wanted to die. But that's just guesswork.
