1) the amount of different and conflicting investigations that this will start and reveal more than anyone would or could ever know, ironically a lot of the people ranting about set ups, will never read the final report. which will be 202 pages long and written in Bureau speak. so I get that .
Secret Service, FBI, Homeland Security, all those oversight commitees, the internal one for the Justice Departmet, OPR or whatever, the postmaster general or whatever he's called, he did a lot of those FBI ones, Inspector General not Postmaster General LOL
2) no one could intentionally miss that shot. There were multiple shots. Truth is stranger than fiction. No one would say graze the president. it's just pure physics that he wasn't killed.
