The police is known to use "non lethal" weapons to mutilate protesters, that's whay they did here, so one teen got a hand torn to shreds from the explosion of a non lethal grenade (don't remember what kind exactly, but anything that explodes is obviously dangerous), another lost an eye due to a rubber bullet shot at their face, and I think another one got their teeth destroyed, things like that.

The riot police blew off a kids hand with a grenade.
