All true - my mother had her stereo (face-off panasonic) stolen from her BMW. They smashed the driver's window, then prised the unit out of the dash (even when a small screwdriver in the right place would have released it cleanly!).

The only satisfaction I got out of it was that they'd managed to cut themselves during this process and so left some blood on the dashboard - at least they suffered slightly. Oh for a DNA register... ;) (not really, I tend to think that infringes on personal privacy).
