[Sgt. Oliver] Tate said there's good reason to sometimes leave the keys in the ignition and the windows rolled down, even if it raises suspicions. "It's about factors that we are seeing in that area," Tate said. "If cars are being stolen with the keys left in the car, left running, what have you, then we try to stay as close to those factors as possible."That's a weird twist on the issue, isn't it? I'd never heard before that there's a state law against leaving the keys in the ignition of an unattended vehicle, and in fact somehow I doubt it, though I don't know why they'd make it up. But even if it's false, that doesn't mitigate the irony of police telling the public something is illegal then going out and doing it themselves.
UPDATE - It's definitely illegal to leave the key in the ignition of an unattended car - see the comments for details.
