For most Americans their home is their most valuable asset. Only about 20% of Americans do anything to protect their home aside from insurance. Why when a home burglary happens every 15 seconds? Homeowners make it so easy.
When the crooks go casing a neighborhood they are looking for homes that looks affluent and places to hide near windows and doors. They want to pick out a home that has no signage about alarms, dogs or security systems. In other words they want no trouble. Fast in, fast out.
