It just so happens that breaking peoples cell phones (criminal mischief) and saying mean words (harassment) fall under Alabama's domestic violence statutes. Getting arrested for it isn't just for football stars either, domestic violence is one of the crimes that police officers in Alabama have no "discretion" in dealing with. It is also, by statute, one of two crimes that police can (and are required to) make arrests for misdemeanors that occur outside their presence.
So in essence, this illustrious al.com writer has very publicly taken the very popular stance that domestic violence laws are too tough. Real domestic violence, according to this reporter, is "devalued" by making other forms of abuse illegal. If the right people took that article to the right places (reddit's r/xx comes to mind) that guy would never get paid to write again.
With that said yes, those protests should've just been a sea of moms beating the shit out of their kids. The world would be a better place.
