I agree cell & corded phones handy, can be assets. My 'firepower' is also handy! In Mich. we have the "Castle Doctrine" which allows us to meet force with force - not only in the house, but also in the car, or in ANY mode of transportation of people or goods! That covers a lot!
I'd like to add that I also keep my car remote on the nightstand - if I suspect an intrusion attempt I hit the horn button on the remote - the horn draws attention, something the BG don't want. My neighbors are aware of this and we look out for each other!
