Can CPS do anything??

*•A•* • In a relationship

So while packing up from the lake, we heard a man yelling at his kids. Their mom was there too but she wasn’t saying anything. But this man was just going off, legit just screaming, “I’m going to beat the shit out of you fuckers if you don’t get your fucking shit together. You know your goddamn bedtime is 9. Stop arguing with me you shits. You better shut that fucking mouth of yours before I beat it off you. I’m going to beat you so hard you’ll be fucking sorry.” And much more. But he was screaming it at his kids in the back of the truck. A couple other people were packing up and just standing there in awe over the scene this guy was causing. I took a picture of the trucks license plate and the man pointing while screaming at the kids. But I was wondering whether or not this would be something to call CPS over and if they could do anything about it or if I should just forget it all?
