The uncle didn’t seem to have any venom, “more in sorrow than in anger”. I got the impression that the news crew cornered the guy and he kinda spilled his guts honestly. He gave me the impression that he cared about his nephew, but could believe “the worst” about him.
Kinney was a hot head and I think the police officer got pissed off and lost his cool. Now we have a tragedy that could have been prevented had it been handled by another unbiased officer...
