Man... that shit is wild. I'm from a country with a different legal system to the US and I cant help but feel like this would be a form of entrapment here(probably not using the term right from a legal perspective). Is the logic in the US that the individual could/should refuse to participate at each and every step? Ensuring they aren't 'entrapped' despite being presented with a manufactured scenario designed to entice crime because they voluntarily preceded? Especially in the second link where the individual was described as 'dim', if we replace the undercover FBI agent with say, a supportive non-radical religious figure in the Mosque, does this young man go on to try to make a bomb?

Really interesting links thanks!
