Yes, free for me. The range was there, and whatever fixed costs are attached to it will be incurred whether I'm there or not. I am only allowed to go during hours when the trainer is already there, expected to finish by the time his shift is over, and not permitted to disrupt other police training. I shot my own ammo, too, btw. IOW, I incur no additional costs by going.
I'm a lawyer, but I'm not your lawyer. If you need some honest-to-goodness legal advice, go buy some.
