I was told of the story by a dog walker. In France people are supposed to carry an auto authorization and their papers during the lockdown and police can attempt to control you.
A grey masked police car apparently attempted to control a jogger by entering the main trail located just bewteen a field and the forest.
The Jogger jumped on the field. The car attempted to drive around the field on the trail to catch the jogger on the other side. But they were blocked by huge rocks placed there to avoid cars using that trail.
And the jogger flew easily away. At his place I would have chose the forrest as the cas had no way to enter it ( you have to jump over a small river or take a some small bridge. but it 's one of the easiest place to ruin the police.
