speaking from experience, crime is definitely up in most if not all areas. it does not matter if you live in the city, suburb, or country. it's out there and everyone is a target.
easiest things for any criminal out there is an unsecured vehicle, building, shop, whatever. if it's open, then it's easy pickings. there's tons of larcenies from vehicles every night. i'd say 95%+ are unlocked. a lot of people feel secure since there hasn't been crime in their area before. well, times are changing, economy is going to ****, and people are becoming more and more desperate to make ends meet.
if you believe you may be a target, you probably already are. being prepared is good though. be sure to lock your doors. install lights to illuminate your access points. take pics of all your items and be as meticulous as you want your insurance company to cover any items stolen. start looking at your landscape. if you've got trees/bushes overgrown or blocking any view from the street, maybe think about thinning those out. all it is, is cover for any would be thief.
if you suspect a crime is being committed, call the police. they may not catch them but it will make them aware that a crime may have been or will be committed. get vehicle descriptions, tags, anything helpful in identifying a suspect.
also some advice on firearms, talk to your local law enforcement. in some places, you can be the one charged if you run out brandishing a firearm. there's also charges out there if you fire your weapon at a would be intruder, warning shot or not. last thing you'd want is to be the one charged for defending your own property. completely different if you're defending a person within your family.
