When I say they in my comment , I mean all of the intelligence agencies that were investigating the bombing and not the Avengers . I agree , it ' s ridiculous that he managed to make it inside as the therapist for Bucky in the first place . Then , after the incident took place , they would have certainly checked everyone in the building . They have camera footage of Zemo in the building , they would have quickly realized that the therapist was different and followed up with whoever chose the original therapist to find out what happened . <| sep |> I ' m also curious . What mental disorders typically falls under the insanity plea cause ? <| sep |> Yep , which is why these kind of stations should always be their own network . Works wonders !
