and it was seen by multiple people in his right hand during the fight/struggle.
Cite these “multiple people”.
Oswald sees the police searching people (he wasn't the first).
All illegal searches without probable cause.
So when McDonald asks him to stand up he doesn't admit to carrying a revolver? Is that what an innocent man does?
Is that supposed to be evidence of murder?
Ruth and Michael were recently accused (again!) in a "documentary" of being CIA agents who framed Oswald; the "skeptics" didn't challenge those claims.
If you’re talking about the Max Good documentary, they weren’t “accused” of anything.
McDonald is first quoted approvingly and then later called a dirty cop.
All of these attempts to defend police misconduct are made by people who ignore what the cop actually said and make up their own version.
The police were looking for a killer who fled the scene of his crime; the 4th amendment protections don't apply in such exigent circumstances. They didn't need a search warrant for crissakes.
The 4th amendment always applies, and they needed probable cause.
