How would the little car thieves have known that the keys were in the car unless they were looking inside of cars to find one to steal? Certain groups in America cannot seem to accept responsibility for their own actions and must always have a scapegoat to blame.
You have the right to leave your keys in your car. But really, in this day and age, what would you be thinking? Feral animals walk up and down the street checking cars in driveways. I see then on Ring camera videos, checking car doors at night. Same as the porch pirates who tail Amazon delivery trucks.
