You're being down-voted because snitches get stitches. Don't be the neighborhood rat.
That ethic is really counterintuitive to me. I'd be really interested if you want to expound on it a bit.
E.g., Are there limits to where you'd apply it? Does it apply to laws that you (personally) do want to have vigorously enforced?
Most people can come to decisions like this without the mediation of a legal system. In this particular case, I don't think that ratting on gym owners who are trying to salvage their livelihoods by serving willing customers is worthy of reporting to the authorities.
Never thought I'd see the day where Americans turn in their neighbors to the state.
We can have a discussion about whether this particular rule really does benefit everyone, but clearly the ones that do should be respected, otherwise what's the point?
