as a french cop it seems completely absurd to me to "breathalyze" a people sitting on the beach. It's even more absurd to punch a 100lbs girl who can be handcuffed by an average man. I'll be fired for something like that. I remember when i was in L.A in a private residence, a guy was drinking a beer at the pool, security came from nowhere, took pic of the bottle of beer, and gave him a 300 dollars fine.
