Nice try. Once your vehicle is booted and served, it shall no longer be operational in the city. Go ahead and remove the windshield after your vehicle is served with a lien by the city and see what happens. There is a difference with tampering with a device that makes your vehicle inoperable because you failed to pay your parking versus destroying or damaging the device. If you think pictures arent taken and you decide to remove the windshield with the device, then go right ahead and do what you gotta do, so will the city.

The boot is there to give you an option to pay so your not jumping up and down how the big bad city disabled your vehicle and you're going to cry to city counsel next. Normally, your vehicle can be impounded for failure tompay but these gadgets are created to help people get their vehicles back asap after paying their fines.
