I'm fairly sure in Minneapolis that they CAN'T tow because of short term registration issues due to city ordnance prohibiting just that. Might be worth reporting it to someone on the city council... provided you have time left.

The city council has shown interest in restricting towing (has done it) and just recently they had one of them on TV talking about towing bad actors.

There is a lot of cynicism further down the chain but it is just BS by people who don't know anything, as at least in Minneapolis politicians have taken action regarding towing.
