I’ll try to say this one more time. Or maybe three more times.
A lap baby is not entitled to a seat.

If you have not paid for a ticket for that specific individual, they are not entitled to a seat. It doesn’t matter if you have bought out every single ticket on that plane for your family members, if you have not bought a ticket for that lap baby, he is not entitled to a seat.
Yes, they could easily check that the other child was not going to be on that flight, if he had already boarded onto an earlier flight. In fact, if you purchase two tickets for the same route, the same day, if the airline notices it, they will likely cancel one of those tickets.
A standby is a person who is trying to get on a different flight, and has put themselves on the standby list for it. Likely the same thing that the family did for their older son, they very probably put him on standby for an earlier flight and he got on. Is it really the better thing to do, to give a seat to someone who had not purchased a ticket, as opposed to someone trying to get on earlier, who had paid for a ticket? And it is likely that the Delta employees who did that would be disciplined for not following the company rules. When an airplane is full, you don’t give a lap baby a seat.
It appears to me that the wife is doing the recording, and the passenger is talking loudly for the recording. As incredibly stupid and rude it is to tell him how he could get arrested and his kids get taken away from him, it’s obviously an idle threat from a young woman speaking weakly to an overbearing man. As if for a moment he was intimidated.
I have no doubt that the employees who kindly (or mistakenly) allowed them to use the car seat on the first flight are going to be disciplined. You see how people who get away with something once think they can get away with it every time. Well, they let me do that last time, so therefore I am always entitled.
