Nobody ever said he was a particular competent hit man. Just that he had access.
So would've lots of people. Almost anyone could've got access to the police station with little effort that weekend.
Do people really believe that after all this effort - planting Oswald in New Orleans, in Dallas, faking photos, firing at Walker, altering forensics, altering photos or whatever way you think the conspiracy was set up - that they were going to leave the final and most important act of silencing Oswald to an incompetent hitman in some clumsy run and gun attempt?
48 hours
after he was captured?
How did "they" know he hadn't sang already?
Why didn't they kill him "escaping" from the TSBD. Or better still, wait until he got to prison and kill him there with ease?
It makes no sense. On the one hand people believe we have this super competent team of co-conspirators who have had this laid out from as far back as '61, whos plan has gone flawlessly up to this point, yet they let a low level hood assassinate the assassin with a .38 shot to the guts?
The first and only hit of it kind. A 90% survival rate. Mobsters and black op crews don't shoot people in the stomach. Its a very silly theory.
