I am sorry I don't agree. He's in his 30s, this girl (and possibly others) were 16 years old. I know in the UK age of consent is 16. But at 16 you are in no way an adult, your brain has not fully developed yet. You cannot go to war, you cannot even drink.
In the US, where the events took place, she is considered a minor.
And on the moral side of things, this isn't the case of a 18 year old man trying to court a 16 year old. He's again in his 30s, he has NOTHING (hi, sarah) in common with a 16 year old other than trying to get in her pants.
He IS a predator. And to me a 16 year old is still a child. So yes, I shall call him a pedalo and it applies to him perfectly.
