have the right is a reason to hit someone

Why is having a right to hit someone a reason to hit them?

Now they should have given him a chance to walk away again but that isn’t a requirement. They can keep hitting him till he leaves.

So you’re saying the police have the right to hit whoever they like for as long as they like, all they have to do is prevent them from leaving the area? That’s crazy.

If they have the to use force, they can and will.

The point is that they didn’t need to use force in this instance.
