I apologize for any glib remarks I made, they were only intentended to demonstrate that I do not take myself too seriously.
If home invasion is a concern for you I submit the following:
Three factors required for a crime are; Desire, Ability and Opportunity.
The only factor we can control is opportunity.
Home invasion is a high risk crime for the bad guys.
If you are regular people and not obviously rich your risk is low.
If you are rich you need to hire me
hinkDeter, Detect. Delay.
Make your home a place that bad guys do not want to mess with.
Lighting, alarms, dogs will deter.
Cameras or good neighbors will detect.
Good locks and physical security will delay.
Go to your front door with a srewdriver and remove the strike plates from your locks. If you have not changed them you will find little screws that only extend into the frame trim.
This is standard, this is why I can kick a door open.
Go to Home Depot, Lowe's or other home store and buy security strike plates, they are much longer than standard and come with 3 inch screws. The longer screws extend into the stud of the door frame and drastically improve the integrity of the lock.
A high dollar lock with a standard strike plate is a waste of money.
I personaly will defend in place if some badguys make entry to my home. I have the long screws, good locks etc.
It will take some work for them to get in. I have dogs. Anyone that STILL wants in after having to batter the door and fight the dogs is most likely going to get shot.
I can explain that to a Grand Jury.
I have been the police for 25 years. I have been in one shooting. I really don't want to do it again.
But I will.
I don't know where you live but your local police departrment may have a crime prevention officer and he/she will come to your home and tell you these things in more detail.
Stay safe.
