How about we just arrest everyone posting terroristic threats before they can do this kind of damage? 8Chan, or whatever public forum these discussions are occurring on.
I keep reading about blimps watching us 24/7, license plate readers tracking everywhere we drive.
Either these terrorists have the best opsec imaginable, or the FBI agents watching the site should consider a new line of work.
A guy like the El Paso shooter driving 9 hours to that city should have been stopped for a “broken tail light” long before he got to his destination.
I find it nearly incomprehensible that the attacker was entirely unknown to the FBI, that they didn’t flag the manifesto, know who posted it, and have the means to know he was, at that very moment, on a long road-trip toward the border.
I don’t personally know how long ahead of the attack the manifesto was posted, or if it was the attacker’s first post. Perhaps those details would mitigate somewhat my exasperation that this attack wasn’t foiled, but I suspect otherwise.
EDIT: According to the NYT it was posted 19 minutes before the first 911 call came in. But Newsweek says an hour and a half.
