So you think your conspirators allowed BRW to see them in the moments just before the assassination and they allowed him to not only leave the floor but trusted him not to raise the alarm and otherwise remain silent for his entire life!
Why would he raise the alarm if they showed him credentials and said they were here to protect Mr. Kennedy? Have you never been to an event where people presenting themselves as security refused you access to an area? If you have, how many times did you 'raise the alarm'?
As for the risk of Mr Williams' talking about them afterwards------what risk? They'd be long gone by that time
you also think they allowed their "patsy" Oswald to be elsewhere in the building where he might have an alibi for the moment of the assassination.
No, Mr Strawman, because Mr. Oswald was not their patsy in the sense in which you mean here: he was not being set up as the sixth-floor gunman
