There is also a vast difference between a single incident and the routine commission of a crime over and over.
From a strictly moral aspect, which is worse? For a 19 year old to find a minor, have sex with her once, use her and dump her, or for two people to be in a committed relationship that is legally inappropriate. I can't imagine a judge looking for kindly on a one-time event vs a repeated offense in this case.
Also since a lot of people have put in their 2 cents here, I thought I'd give you all an update. After some research, I found that since I'm NOT a mandated reporter, I am not required by state law to report ANYTHING. As a matter of fact, according the Lewin Group even a mandate reporter isn’t required to report this. They have a Statutory Rape guildbook online that states:
"However, mandatory reporters are only required to report
consensual sexual activity involving minors under the following circumstances:
• Unlawful sexual intercourse when the victim is less than 16 years of age and the defendant is at least 21 years of age.
• Lewd or lascivious acts between a minor less than 14 years of age and another minor of disparate age.13
• Lewd or lascivious acts where the victim is between 14 and 15 years of age and the defendant is at least 10 years older than the victim.
• Sexual penetration where the victim is less than 14 years of age and the defendant is more than 10 years older than the victim."
The citation they used was California Penal Code Section 11165.1 which is where sexual abuse is defined. I read it and couldn't find anything saying what was stated above, so I can only assume that there is some precedence for their statement. I would like to reiterate, that I do not think there is an ethical violation going on between my roommate and his girlfriend, just a legal one, so if you are going to come back at me with attacks about how horrible a person he is and I am for allowing him to roam free, save it. I AM concerned with doing the right thing legally so if you have information contradicting what I've found, PLEASE let me know.
So since I am NOT required by law to report them, the only risk I was taking was allowing to happen where I live. Of course, I couldn't technically ban anyone he wants to coming over, but as I said before my roommate is a decent person and telling him the risk he was putting me in was enough to get a promise out of him to stop the visits. Which apparently led to a fight between the two of them where she broke up with him yesterday. Of course we all know what teenager break ups are like so I don't necessarily expect that to last, but I think I satisfy all the legal requirements of me, right?
