I'm unsure why the BBC has put an upsetting scenes warning on the video. Nobody got hurt, they are just disappointed. I think this is far preferable than those people going across the sea and potentially dying in the water. The police wouldn't have done it if it wasn't shallow enough to safely stop the boat. I think they are very brave.
I wonder what the French will do with the people though, if they are now serious about stopping boats.
