Not being sexist here. By girl I literally meant the teenage girl as shown in the video or a teenager generally. I should've said a weak and scared person who's obviously incapable of defending him/herself nor willing to fight back.
From what you said perhaps sadly it does happen in France too.
I understand what you meant. And there is a sexist bias where hitting a teenage girl or an old lady is worse than hitting pretty much anyone else.
But that's not what we talk about most here. The main problem is more the general scare tactics. For instance with the Yellow Vests movements, there were several instance of the cops encircling the protestors without giving them an out, and then they threw tear gas at them. This terror technique is not just scary and uncomfortable, it's pretty darn dangerous, just because people get so tightly packed together. (One can be chocked just by the pressure).
But it's not as bad for PR as hitting a defenceless teenage girl.
Our police force is significantly more violent than the German one, and I think the English one as well.
