^Elvis was a predator, he committed improper sexual acts with a minor even if Priscilla "consented" it.
Well if you want to keep it on the legal side of things (which I assume you are given the embedded video), they might've been within the law for the most part actually.
Priscilla and Elvis spent a lot of time together from September '59 to March '60 in West Germany. At the time, Priscilla's age of 14 was the minimum age of consent in West Germany and, if you were over 21 and performed sexual acts with a 14 or 15 year old, you would only be prosecuted if the parents complained. Priscilla's parents never said anything about anything.
The next time they saw each other was Summer '62, by which point Priscilla was 17. Judging by Wikipedia, it seems they spent most of the time here in Nevada where the age of consent is 16 (although Elvis did trick her parents into believing they would be in Los Angeles instead - related or unrelated take it as you will). In March '63, she moved into a separate house with Elvis' parents at Graceland, Tennessee, where the age of consent is 18. A few weeks later, she moved into the main house with Elvis and within the next month or so she was finally "of age" in the eyes of the Californian law.
Assuming they did spend most of their time in '62 in Nevada, really the only time the law might've been broken is in the month or two leading up to her 18th birthday in '63. Not saying that legal=fine or illegal=bad either, just talking about it in the context of the law. Priscilla states they didn't have sex until marriage 3-4 years later and while the arrival of Lisa-Marie 9 months after their marriage does perhaps add some credibility, I really struggle to believe that. I mean, they
were living together all that time and it's really hard to believe they didn't do it
once in that time.
I'm very mixed on how to feel about this whole thing. I find the first few years really creepy but beyond that... from what I have read, I haven't seen much to confirm they actually did anything sexual in the first few years and never-mind they spent most of the first few years apart. I read that Elvis had sexual affairs with more reasonably aged women during the first few years and on top of all this, Priscilla has had almost 60 years to speak out against Elvis but hasn't. Then again, it's not like she's biased towards Elvis or anything, nor is it (obviously) impossible for such acts to have happened... and how many people apart from Elvis/Priscilla would actually know? Maybe her parents but they're long gone now. Like I said, I'm very mixed on it all...
