This was also the day I committed to carrying every day. I hadn't been bringing my carry gun to work so I was unarmed when I walked in the house and I had my 2 year old behind me.
It took 5 minutes to get a 911 dispatcher. About 12-15 mins more to get a patrol officer there.
I bring that up to people who say "just call the police".
Then I ask them how many times they think they can be stabbed in that time.
