I noticed your tactic is based on an “intruder”. How are you determining this? Do you have a camera system? Crystal ball? Or, are you just basing it on your own fantasy of how your home invasion scenario will go down? Will your plan be as effective on “intruders”? Will they all be in the same room or will they split up after gaining entry? Will they all be in the house or will someone be outside as a lookout? Do you notice all the question marks in what I wrote? Your plan doesn’t have enough question marks. I hope for your sake you never need to test the efficacy of your plan.
