What makes him dangerous is filling his head with dangerous thoughts.
What makes him danerous is that his head was filled with dangerous thoughts BEFORE the FBI ever spoke to him. He had stated his interest in Jihad, killing, and dying for the cause. He demonstrated his willingness to carry through his stated intent and actually attempt an attack. Youve got this wrong.
The vast majority, if not all, of the people whom the FBI have entrapped in the past are some of the more vulnerable members of society: people without a strong social support structure, part of a marginalised community, often poor, often unemployed, and so on.
That's a fine assertion. Do you have any proof? There have been at least hundreds of arrests and convictions for offenses related to terrorism. If what you claim is true there should be some proof.
Do the poor, unemployed, or marginalized have a right to engage in terrorism? Is there some reason they shouldn't be stopped from killing people? Aren't the rights of other people in society to not be attacked equally important?
It's a fundamental axiom of modern policing that the best way to stop crime is to stop people from becoming criminals in the first place. If someone is at risk of becoming a criminal, the best thing you can do is divert them away from that as early as possible.
If you bother to look into this, including the story I linked to, you'll see the FBI tried to divert him. They got him to a Muslim cleric to try to talk him out of it. He persisted.
For the FBI to turn a non-criminal into a criminal is not just a failure, it's sociopathic.
You are fabricating things out of whole cloth. Is there a DSMV label for that?
