I don't trust the FBI, I've seen first hand what they can do to people. They hassle people, usually going after us in our teens or 20's who are easier to manipulate. They rarely go after the older people, they go after youth. Look at all these guys who get supplied and arrested by undercover agents with fake bombs, they're usually 15-30.
I converted to Islam like in 2008 and never in my life had run-ins with the FBI or the governments until then. All of the sudden agents are coming up to me, these dudes came up to my college to question me, followed me to my crib at least twice. When they question you, they play mind games with you and try to scare you into answers. They turn your life into a movie. One thing that stuck out to me about the agents I've seen was that they seem really obsessed with creating imaginary grandeurs international conspiracies. They act like every Muslim know every Muslim and everybody interconnected.
Look at how they keep saying "Chechnya" this "Chechnya" that "Chechnya". Everything they do is designed to implicate as many people as possible to justify overseas campaigns, drone attacks, etc. Most of the people killed in the "war on terror" don't even have nothing to do with 911. They'll connect random people/groups with no affiliation whatsoever and I've seen it first hand dealing with them so could it be a frame, absolutely. And could they manipulate the situation to go kill some random people overseas, MOST LIKELY. Look at how the US-Russia are suddenly cooperating, this went from two guys possibly bombing Boston to two countries uniting against an entire republic of people.
