> After watching some videos that showed just how easy it is to simply kick a door in, another thing I did was replace my strike plate with a heavier duty one, and replace the worthless 3/4" screws that "hold" most strike plates in with 4" screws that actually go into the 2x4's of the house frame. This is good advice. I did this on my own door frame after being broken into on the first day where the door had simply been kicked in. I can not kick the door in now - I tried. Although the quality of the door is important too - mine bends really quite far before breaking. :) If you are really security conscious and you don't have them already - I suggest brushes at the door frame edge and the letterbox to prevent approaches other than picking.
