The best thing you can do to protect yourself is to make it nearly impossible for the criminal to kick in the door. This is accomplished by putting a barrier in between the wooden door that acts as a privacy screen and the outside world. Iron entryway doors are nearly impossible to breach, and welded ones like the types that we produce are even harder. The iron is nearly impossible to cut without a blowtorch, and the welds make it nearly impossible to break through with a hammer. The criminal would have to take a long time working on the door in public to get through it, and this is usually enough to make a thief move on to the next target. Criminals are opportunistic, meaning that they will almost always choose targets that are without risk of them getting caught. Put up an iron barrier that they are going to have to work to get through and make a lot of noise doing it, and most criminals will choose to move on to the next soft target.
It is nearly impossible to completely prevent crime. The way that you have to think about it is that if you make the criminal's life difficult then he will move on to the next target that is easier to hit. This is not going to reduce crime in your area in general, but it will reduce the amount of crime that happens to you. Through the installation of iron entryway doors, you are going to take away the advantage that they have at gaining entry into your home using the weaknesses that they have experience with. They are going to move on to the next home that exhibits those weaknesses, and while this is certainly a sad state, at least it isn't going to happen to you and your family.
