While that did happen, the park they were playing in was closed, and the man in question refused to produce ID when requested.
The man was held for ~10 mins in the cop car, and then released. And the PD apologized publicly the next day, pledging to complete an internal investigation. So hopefully this was an isolated overreach, and likely, one that was used as a cautionary tale to many PD's across the country.
We're not far from some rural areas. Early into the stay at home order, a man was almost arrested for riding his ATV. After law enforcement realized the man was on his own property, they backed off. Law enforcement admitted that this whole business is an unprecedented gray area and they really weren't sure how to handle a lot of situations. It wasn't said who reported the man in the first place.
