Drinking laws aside, an 18 year old is adult enough to enter the military without parental consent, they can also get a passport without parental consent - two very adult things our society allows when you're of age. It's also the age when you face adult jail for crimes that would normally be swept under the rug if you were "a child" (17 and under). If you're old enough to know better and choose not to, you don't get a pass. Same way I don't buy if a 18 year old murders his girlfriend, parents, they knew what they were doing is wrong when they did it anyway, a six year old child doesn't, and a child under the age of consent, can't consent to sex with an adult. I hope they throw the book at this person. No one that's 18 should be able to use the "I'm too young to know better defense." I'll bet she has a driver's license...another adult act.....not buying it.
I know if this was my child being sexually molested, she'd have bigger concerns than the courts.
