Police do not prevent crime, they apprehend people that they then accuse of doing the crime.
When you have somebody actively looking to steal $THING, they will find it and steal it.
You do not see these massive Kia/Hyundai thefts in countries that mandated immobilizers in all new vehicles.
So it is a failure of policy, not policing.
