For what it’s worth, being mentally ill has absolutely nothing to do with whether or not that AK47 was a Fast and Furious (or similar operation) gun.
And being mentally ill does not mean the shooter is NOT associated with a drug cartel who might be looking to take down someone who they had concerns about.....some National Guardsmen, for example, who might have learned something they shouldn’t have.
And what is Sencion’s religion, for example? Has it changed recently? I understand that jihadists find mentally ill muslims easier to recruit for suicide missions than sane muslims. That makes sense.
I will leave the wild speculation to you and I will wait for facts.
