Of course not, but the discussion should maybe include some more questions and less pronouncements. For instance, the people who shot the girl were almost assuredly bloods, because it's close to their territory. The place where the shooting happened is the lower east side, which has been a home to countless immigrants, but has lately been taken over to some degree by hipsters. The street that it happened is not a main thoroughfare, but a smaller side street that is more narrow than most streets and not all that well lit.
Etc. etc. etc.
That should be true of almost every discussion thread on this forum :-)
