Simple efforts can reduce the opportunity for crime.
If you have a security alarm, use it!
Keep outdoor lights on.
Physically check that windows and doors are securly closed and locked.
Keep curtains closed.
Make sure vehicles are locked and valuables are out of sight.
If your schedule has you arriving at a late hour, tell a family member, a friend or co-worker to expect a call, a buddy call system.
You are the best judge of what is normal activity around you and your neighbors.
If it looks supicious, it probably is. Call 911 with a good description, shoes are a good item because they are harder to change than a shirt, coat or pants. DO NOT CONFRONT SUSPECT.
It is better to call about something that is innocent than not call about something that is guilty.
