Its very complicated. Especially when the difference are marginal. like where there is a difference in the age of consent.Crossing state lines is breaking not just one state law but other states as well and it makes it Federal instead of local. In short they are breaking more laws by going to other states.
A child may be under age in one state but not in another one.
Prince Andrew did not break british law by sleeping with that 17 ear old girl. He just broke the laws of decency.
