"I was never talking about a police investigation. "

Yes, I know that, hence my comment that you prefer assumptions over investigations. Was my comment not clear about that?

You are free to make assumptions based on early reports, and many times those assumptions will be wrong. Like they were wrong in the Portland train stabbing. My comment that it is too soon to know is correct, if you care about facts and truths. If you don't care about facts and truth, by all means, have at it! You certainly have plenty of company here!
