While Reddit mods and admin try to keep up with the site's "no violence" terms of use, Facebook and LinkedIn is reacting with tens of thousands of laughing emojis.
I've been pretty impressed that the shooter has so far evaded police. I can only imagine that there have been at least one or two incidents thus far where people, be it cops or witnesses, had a clear opportunity to take actions that would lead to his immediate capture, but decided not to.
From what I know, cops often rely on the cooperation of the public to resolve crimes, but they may not be getting any on this one.
