If you don't come quietly then we will handcuff the child.
The child obviously has no intention of going.
Now of course I have no idea of the rights and wrongs of this specific case. But it is apparant that the child isn't being coerced to stay.
When two officers force him to the ground to cuff him, one of the police, before knocking the camera to the ground attempts to block the father from filming the scene by waving his sheet of paper which gives him authority.
Of course this is done for the good of the child now, isn't it.
