FBI/ SLED testified (direct evidence) to bullet holes with trajectory pointing towards the dormitory. I don’t think you can claim NO evidence. I’m not arguing good guy/ bad guy. I am suggesting you oversimplified this event to suit the narrative you wanted. The truth is almost always somewhere between. At common law arson warrants deadly force.

If we had used the opportunity, the blm Riots could have been shot down much earlier with far less damage done
