You might want to look back through the old threads. Posting private messages is not against the rules as proven by several users posting your daughter’s threatening messages to them. The Kanarek tactic of empty threats doesn’t work here whoever you are.
I agree. If the gun had still been in the safe where MB had placed it after receiving it from RC, why would LK have been taunting RC about her “missing” gun?
With MB’s memory loss we can’t be sure, but it is possible he wanted to get into the safe that day to verify if it was still there, not to take it to the house.
