While it disappoints me to agree with Crepitus, Crepitus is correct. No pardon, whether Presidential or Governor, eliminates any crime committed. It only says they are free to go back to their lives. They did have to pay a fine, which they did. That in itself, just like paying a traffic ticket, is an admission of guilt, to some degree. The important thing is that they can go back to their lives as if this never happened......AND......get to keep their firearms for the next Communist mob.
Back when this all occurred, they should have just stayed in their homes, recording the actions of the mob and if the mob broke windows and otherwise damaged their property, they would have had ample evidence for an arrest and if the mob literally broke into their home, then they could have gunned them down as they came in.
In the Supreme Court case of Ex Parte Garland, The Supreme Court ruled that being pardoned releases the punishment and blots out the existence of guilt. BUT.....in this case they accepted the misdemeanor charge and paid the fine. The pardon wasn't for the misdemeanor, but rather the more serious charge of "assault." The misdemeanor remains on the books.
