"... but a locked car is not much of a deterrent. '



Here is a current story. I'll quote some highlights within.

Police said last week that they had arrested five people, all current or former Kirkwood residents who admitted to more than 200 thefts from vehicles and the theft of more than 15 vehicles.

Each of the stolen vehicles had vehicle keys left in the car left by the owners, police said. All of the vehicles were recovered.

None of the vehicles were actually broken into, either, police said — the vehicles were left unlocked.
