Unfortunately, like others have stated, residential burglaries are almost an epidemic right now. And solving the cases is quite difficult, even though most victims know the offender. Gun safes will prevent the guns from getting taken in 99.9% of cases. Once entry has been made, they take things of opportunity. And the burglars are conscious of time spent in the house. A bolted down gun safe is the best thing you can do for the safety of everyone.

As for everything else, record serial numbers! I have the SN's of everything in my house of value written down in several locations on several hard drives (Including my work hard drives!). In my city, if you report your laptop stolen and give us a SN, it will flag whenever someone pawns it. The next day you get your laptop back, and we get an ID of the person who pawned it. Having the SN of your computers/TV/guns on file increases the chances of catching the suspects by 80%.
