A 40-year-old man had an 18-year-old girlfriend in west Philadelphia. He was shot and set on fire by her parents.

A 22-year-old man met an 18-year-old girl in Massachusetts at her dorm in college, where 25 guys waited and beat him, until he managed to escape and call the police. They said 22 and 18 is a predator and pedophile.

pedophilia is a psychiatric disorder. The older person needs to be 16 or older, have fantasies about prebubescence for at least 6 months and the younger person needs to be prebubescent (5-11 for girls, 5-12 for boys). Nowadays, the decoy always pretend to be 14 or 15. This is not pedophilia. If you claim a person on this show is a pedophile on that case, he can actually sue you because it's a false accussation that can cause a lot of harm

Realisticially, as long as both are adults, it doesn't matter. If the age gap is big, like in asia, then it is often a transactional relationship. But in a woke world where nobody understands what the definition of a pedophile is, everything is a pedophile if they are more than 2 years apart. So wether you are safe to date depends largely on culture. Chris Hansen and Law Enforcement won't care if you wanna date a 20 year old as a 40 year old

TLDR: As long as both are adults, it depends on social acceptance and culture with age gaps. Bth cases you described are normal relationship dynamics in asia

Even found that clip of Chris Hansen at 16:55. The constellation is a 22 year old dating a 39 year old. Chris Hansen just says "Yeah, she's an adult". So age disparity is really not a concern of Hansen. I believe he also had relationships with similiar age distances, alltough the woman is in mature adulthood not young adulthood

But really, just pick someone of age, see the social climate and chill man. You won't get in trouble for dating an adult
