The officer was not rude. He was polite and proper in the correction of what he thought was a violation. That was never the issue, although we think it strange to be asked to swim another 25 feet out to the MP boat and to have to hang onto it in deeper water while signing acknowledgement of the so-called verbal warning and being required to provide name and birthdate. The issue is interpretation of the law, which obviously will not be settled here. We will contunue to use snorkels while swimming, not diving, in the privacy of our own cove/shorefront since that, we believe, is perfectly legal behavior. End of story.
