Law on sunpad use...?

So we were out having a hassle free time on the lake and decided to call it a day, so we headed back to the launch. We were idling around the dock, and proceeded to the dock to drop off someone to back up the trailer. As we were idling towards the dock, one of the members of our crew way laying on the middle of the sunpad. Out of nowhere a sheriff truck towing a boat stormed the ramp and a deputy and another officer came running down the ramp, pretty much like he was going to draw a gun on us. This was the most disrepectful and rude officer I have ever encountered, and after doubting the validity of my boaters safety license proceeded to tell us, after scolding me the driver and the passenger on the sunpad, that he stopped us because it is extremely dangerous for someone to be sitting there, because they could easily fall off and be injured by the prop. He didn't issue a ticket; just left a really bad taste in our mouth about the whole afternoon of boating.

Which brings me to this... has anyone else been hassled by this issue, or have any input on this? I also am questioning if this is a law in MI or not. I understand that the swim platform would be an issue with the motor running, or even the pad at any speed above idle, but we didn't even think we were doing anything wrong here...

What do you think wakeworld?
