It does seem very excessive tbf.She's a small teenage girl.I'm pretty sure he could've just picked her up and carried her out in a controlled way.Yes the desk may have made it awkward but that looks to me like he lost his temper.
Obviously we need context though.She could've threatened him or something before hand.
Still you would'nt expect to see that kind of force used on anyone let alone a teenage girl unless they were physically attacking him.If i was her dad i would go and beat the **** out of him tbh.
