)The guy with the gun is a cop called a gendarme investigating some surly youths up to no good; the youths are black, but they don't have a noticeable "Muslim" accent (or North African... lots of black Muslim folk in France are called "pieds-noirs" and have a distinctive way of speaking.) It's towards the end of whatever encounter there was, so I don't know the context of why he's there, but the narrator starts by saying, "as the gendarme is leaving, they throw glass bottles at him. As he's leaving, the policeman's thoughts turn to the worst scenario." Then the dude comes up with a bat for no reason and the cop says, "what are you doing with that bat!" The youth then apparently takes a cue from all the thugs in America and says, "touche-moi avec ça, 'shoot me with that, man, come on, shoot me!'" The narrator says, "the gendarme with his hand on the weapon does what he needs to to not shoot the young man." "Turn back, walk backwards away, you all are acting like fools." Then the youths puff up and say things about his grandma I can't write here (literally!) The narrator says that the cop's main worry is to make sure that the cameraman and the people on the street make it back to their cars 100 meters away without being hurt. The youths shout, "you come back here, we'll beat your heads in with this baseball bat!" Then the cop says, "you can make it to the cars from here."
Interesting video. If they are Muslims who just speak good French, it shows the problem France really is facing now. But Muslim or not, that cop showed a lot of professionalism and restraint!
