evidence: Anonymous Secret Service agent claimed he "had the assassin in [his] sights for at least 3 minutes" on the 4chan bulletin. [...] The post, allegedly written by Willis, alleges that he was one of the officers present at the rally during the shooting. Although Willis had the shooter within range "for at least 3 minutes", there were no instructions from the top brass of the Secret Service to neutralize him. [...] "My name is Jonathan Willis. I'm the officer in the famous photo of the two snipers on the roof at Trump's rally. I came here to inform the public that I had the assassin in my sights for at least 3 minutes, but the head of the secret service refused to give the order to take out the perp. 100% the top brass prevented me from killing the assassin before he took the shots at president Trump," he allegedly wrote on 4chan.
