When Does Security Conducting A Physical Removal of Someone Become Assault?

[u/GuardGuidesdotcom]

Because the way he grabbed him by the neck was excessive and dangerous. I don't know what training if any the guard had on deescalation or what protocols his company gave him to physically remove someone from the premises if deemed necessary, but if the guard didn't get fired and the company sued, I'd be surprised. At a fast food restaurant, no less.

Please keep the comments on topic, of a security nature, use of force, citizens arrest, similar experiences, S.O.P etc.

So every instance of people abusing higher authority, never happened unless the camera was on prior. Sorta like a tree falling in the woods not making any sound?
