How many do not sign up for the Selective Service when it's the law?

At one time it may have seemed more like the 'thing to do' than nowadays. When I was 18 I recall getting to the SS office as soon as I could to register, feeling it was somehow my duty or obligation to do so. There was still a draft at the time.

My senior year of HS, we had to take a US Government class. In that class, towards the end of the year, they passed out the registration cards and walked through the steps on how to fill it out for all of the males 18+. It took maybe 5-10 minutes max of class time and I don't recall any guy opting not to do it - it just seemed like a normal part of being 18 and "growing up".

Shoot, I was on the DEP waiting to leave for basic training and I still did my selective service stuff. Doesn't surprise me that there are people who don't know though. I don't remember ever really being told about it in school at all. I knew about it from my parents and others that I had talked to. I wouldn't be shocked at all though to find out people I know hadn't done it, in fact out of the men in my high school class (of which I think there were 9 or 10 of us) I can think of one or two other than myself that probably did it on time. The rest I'm not so sure on.
