He continues to raise questions about the FBI's role based on evidence from the many mass shootings.
The FBI often opens these cases when suspects with questionable mental health make statements online or to friends, family, or co-workers indicating possible support for terrorist groups or terroristic aspirations. Comments could range from claims of belonging to a terrorist group or expressing a dislike of or a desire to cause harm to certain groups.
Instead of recognizing a potentially dangerous, mentally unstable individual and getting them the help they need, the FBI instead proceeds with a process of entrapping them. They work often for months posing as terrorists, gaining the trust of the suspect, and leading them through elaborate, scripted terror plots.
So elaborate are these undercover investigations, that in at least two cases, FBI informants would actually train suspects how to use real explosives and even practice detonating live explosives in remote areas in the lead up to the final "attack."
