Biden's son had committed and was convicted of a petty crime that is basically never enforced.
The pardon was sweeping.
You seem to be arguing semantics. I care about what his son actually did. If someone is sitting in jail for a marijuana conviction, and gets a blanket pardon, I am going to say they were pardoned for the marijuana conviction, not for some theorized other crime.
You don't get a blanket pardon for a marijuana conviction. You get a pardon for that exact crime. No one gets a blanket pardon. That is my point.
Because, again, Trump was explicit he was going to go on a political witch hunt to target his enemies. A blanket pardon is your best defense against manufactured charges in that case - see all of the current cases being brought against his enemies.
I don't really understand why this is a difficult concept for you to grasp.
