Since all of these shooters seem to be “known to authorities”, then haven’t they, already, in a way, been red-flagged? What is the point of giving authorities a head’s up when they can’t do anything about it anyway?

"Known to authorities" is not sufficient to lock someone up or to violate their rights.

I would be surprised if everyone who posts on freerepublic isn't "known to authorities".
