I suggest putting Swagger under FBI surveillance the day of the shooting (at the Post Office). If he is monitored by the FBI or another organization, it will become impossible for him to make this shot. This will then make him automatically innocent of the shooting. You can also inform Bob lee of his situation.
Bob Lee's situation at this time is completely different from what he has in Shooter. we know that he was 40 years old at the time of the conspiracy. This gives a Bob lee 33 or 34 years old, this gives a better physical condition too. It is also normally still active. you add to that the resources available to Alex and you have a commando sniper, very dangerous that it is better not to annoy.
