Interesting current IF debate

I came across this article (http://www.sun-sentinel.com/news/local/florida/orl-raunchydvd1707may17,0,6950550.story?coll=sfla-news-florida) the other day and thought that it made some very interesting points. The article discusses the borrowing of rated R movies by public library patrons who are under the age of 17. The article highlights the debate as to whether or not those under 17 should be allowed to borrow rated R movies from a library when they would be unable to see the same movies in the theater. Now I firmly believe that librarians should not police what people are checking out and that this responsibility lies squarely with the parent but you have to admit, it is an interesting point. If a child would be unable to walk into a movie theater or video rental store and watch or rent a R-rated movie, why should they be able to walk into a library and to the same thing? I don't have a good answer for this quesion but am curious to know what others think. I believe that a healthy dialog and open debate may be the only way issues like this one are resolved.
