Like Clouseau and Kato?

This is a scary scenario.
I've thought about this kind of ambush being a real possibility.

I have a button that opens my garage door mounted on the wall next to the door leading from the house into the garage and I open the garage door from the threshold of the doorway - before I've even stepped out of the house and into the garage.

If someone came charging into the garage, I'd just take a step back into the house and slam the door. Drawing my CCW would be the next immediate step. Pressing the panic button on my alarm system would be the next step.

I may switch my routine to wait until I'm in the car and set to go before using the remote to open the garage door. I already back in, I think I need to encourage my wife to do the same.

Gonna have to spend a little time thinking on this one.
