And then they hit the emergency shutdown, which is for when people have a plate in their head and they're stuck to the side of the machine. That one causes all the liquid helium to be quenched, thus needing to be refilled.

There is a slower shutdown that doesn't do that, but, you know, cops.

Every detail of that story was worse than the last, and it's 100% on the cops.

Edit: forgot another detail. The gun is probably magnetized now and might be unsuitable/unsafe for use anymore.
