I ctrl-f’d the page for the word “beat” and found nothing. The only claims I see from the daughter or the father (I’m ignoring police claims) of any physical contact with the father are that he was pushed against a car by “nine or 10” of the 8 responding officers who were also arresting her, and then pushed to the ground.
In the hospital photo provided by the family, I see no bruises, abrasions, or other injuries consistent with a “beating”.
He interfered with the officers attempting to arrest his daughter, who had just threatened people with a baseball bat; a deadly weapon. Both pushing against a car and pushing to the ground are reasonable uses of force in detaining an uncooperative subject.
It seems the daughter went bat shit crazy in the store, threatened employees, police responded in force, and dad got between them and the violent criminal they were there to arrest. He was quickly arrested by some of the cops while the others arrested the daughter.
What do you think they should have done differently, once the daughter had began threatening people with a deadly weapon?
