he's a liberal -- the gun did it
Hell, maybe it was the rittenhouse verdict or the george flloyd incident that was ultimately responsible...
institutional racism perhaps?
All we know is that he's a liberal and therefore the responsibility will never fall on 'personal'..
So the trigger magically pulled itself? Being that "Rust" was a western, we have to assume the pistol was a single action Colt Army. Therefore, the hammer would also have to magically cock itself before the trigger could decide to pull itself. Old Alec must be on some hefty meds if he thinks anyone believes him.
