wonder what the outcome would have been had Dr. Petit had firearms in the home...

This is all I could find on how they gained entry:

Joshua Komisarjevsky spotted Jennifer Hawke-Petit and her two daughters at the store and followed them home, then returned later with his friend Steven Hayes and together they broke into the house and severely beat Petit and killed his wife and daughters, investigators allege.

If this happened to me I would make it my life's work to exterminate the killers.

Probably nothing.

He was sound asleep when the perps came up and beat him senseless on the front porch. The they took him to the basement and tied him up.

What they did to the wife and two daughters was unpeakable. It was far, far worse than Truman Capote’s “In Cold Blood”.
