This behavior goes beyond strict parenting the father is acting inappropriately. Mind you, all of this is simply because she refused to share her phone password.

He should be teaching her its not ok for any man to treat her like this. What a jackass

Who is filming this? Are they gonna show this to the police????

This dad need to be in jail

Uhmmm CPS?

He must be a cop.

Well that's one way to have your child cut you out of their life. Then again, he seems like the kind of guy who would sooner blame her than look inward, so yeah

In 10 years on Facebook: "My daughter has stopped all contact with me, I don't know why!"

This is fucking creepy as shit....

Just don't give them a phone if your gonna be this shitty.... 

Or just take the phone away permanently. The anxiety of being away from a phone is enough to get her to give him the password. Jesus Christ this is creepy.

Fuck this guy. 

The fuck is pinning her to the ground supposed to do? Is dad the lasso of truth that will make her spit it out? How hard is it to respect peoples privacy.
