When in Rome

In Finland we have a TV series called 'The Police' ('Poliisit' in Finnish).  It follows police patrols during their shift, mostly in night-time. Usually there's just drunken drivers and all kinds of night-time weirdos.
   This video caused some amusement among my friends in Facebook (partly because Kuopio is the closest big town and you can imagine how we countrymen deal with them). In the video Kuopio's police interview a man, whose face is covered on blood.
  Here's the translation:

Policeman 1: "Why are you messed your face with that blood?"
Man: "I drink it."
Policeman 1: "You drink it? Well, it's quit unusual way to drink that blood, 'cause it's messed the whole face."
Man: "I drink like this. (Shows)"
Policeman 1: "So you pour it from high to your mouth. Ok."
Policeman 2: "(Tells over the video) It didn't come clear to me that why he had been drinking. He just said he had to drink. And especially by pouring it from high, not by drinking from the bottle. Just pouring from high straight to his face."
Policeman 1: "(On the video) Ok."
Man: "But usually I do it out of sight."
Policeman 1: "Yes. Like propably this time, but the result is that kind of it might scare people. Now is best you go to home."
Man: "First..."
Policeman 1: "First what? First what?"
Man: "Have to wrap a cigarette."
Policeman 2: "(To his partner) Three and half permilles."
Policeman 1: "I don't know if he can go home."
Policeman 2: "Yes. And especially if he's going to stay there. I doubt it a bit."
Policeman 1: "(To the man) Well, we were thinking it would be better to stay with us the next night. You should start to go right away. You can wrap while walking.That was a bright idea."
