I don't know about your lawyer - but you will get an answering service in the middle of the night - unless you have a personal number that said lawyer will pick up.
You want to roll emergency services first. For the what if game - the BG is shot and bleeding, it will look great that you were chatting with Perry Mason as they died.
The neighbors might have heard shots and the law is arriving with no knowledge who is the good person. Would you like them to know that?
What if you were shot or hurt? Your family?
