the man tried to gain entry into his house, you are allowed to defend yourself and your property.
if someone was trying to open your door at 4 am would you feel threatened jagson?
I've experienced it many times, and I can tell you feeling threatened, ...and BEING threatened are two different things.
When I had my Harbourfront condo, there was a guy who constantly tried to get into my place at 2, 3, sometime 4 in the morning. He was always drunk, and mistook my door for his. I'd always walk him over to the other tower, and get him inside his place.
A few years later while living in the suburbs, my mother decided to hop on a plane and fly to Canada, and not tell anyone she was coming. By the time she landed, got through customs, collected her luggage, she thought it was too late to be calling, so instead she just arrived at my house, and tried to get in through the garage at 4 am. I was awake at the time, all alone in the house, and definitely heard someone trying to gain access via the garage. She figured she'd come in via the laundry room, since she had a key to the laundry room door. I was on the phone with 911 at the time, and knew that even though the intruder had gained entry into my garage, there was still another barrier they had to get through, ...and potentially many more barriers within my home, if they breached the laundry room door.
Just because I FELT threatened, didn't mean my life was in danger at that point.
Had I simply done what Hendrix did, and shot at a silhouette, my mother would not be here today.
