Look of someone is going to break into a house or a car they are going to break into a house or a car.
Locked or not they don't have the ignition keys so the intention was already going to be hot wiring. Do thieves really let something like a locked door foil them? Not like you can Google or you tube how to get into a car is it 
They aren't going to give up cos the doors locked if a car has a high street value.
Same as no one's going to get some mates together a vehicle together turn up to a house they picked months ago as they know the old lady inside is pretty much deaf and the only it messes are likely to be the local druggies who wouldn't go to the police anyway and say "ooops doors locked let's go home"
It's why it's called breaking and entering.
The lock is really the only thing that stands between insurance pay out or no pay out.
Pushing the problem onto someone else is not prevention.
If an area or person was chosen as a result of the fact that area is renowned for being one where police couldn't catch a cold or the victims likely to be someone who couldn't go to the police or they know the cameras have been broken since 2003 then the reasons for the crime are there regardless of who you push it onto
