Another article, "feds arrested mass shooter before with terror manifesto, but failed to warn local authorities…" hmm what did feds do with the man? Why are so many mass shooters known to feds prior to their mass shootings? You know those questions about "didnt they see the warning signs?" Maybe the warning signs aren't warnings to the feds, but an indication that the person might be useful. You know, like Amber Alert is used by pedovores.
