Well yeah, that is the evidence one random thinks is compelling. It gives insight into how some people think, and like I said I feel third-party embarrassment for them. A cop could literally be a Jeffrey Dahmer copycat, and it wouldnt be generalizable. In this specific case there is zero evidence of criminal wrongdoing
So no, obviously, woman goes on date with a cop and ends up dead isn't evidence of all cops being of a particular demeanor, any more than a police chief misusing a camera is evidence of cameras being bad for freedom. But Flock cameras are bad for freedom, having a huge potential for misuse. And cops have a huge propensity for domestic violence and dangerous behavior towards their partners. Ample evidence exists if you care to look.
