You can do this by not making yourself an easy target for criminals. Most criminals are looking for an easy target to victimize. Criminals don't like to work very hard to obtain their desired, unlawful ends. You must acknowledge that criminals come in all shapes and sizes, male or female. Don't let appearances fool you.
Criminals act, think and behave differently from normal people.
They can be very unpredictable and can suddenly change. Keep doors and windows locked at all times. Doors should have a one-inch dead bolt and a door viewer. Look before opening your door to anyone. Leave outside lights on at dark.
