All you do by nofollowing is create a situation where you're trying to manipulate PageRank that does no good whatsoever, since 4 or 5 (I think) years ago when Google started "counting nofollowed links" for PageRank passing purposes even though they didn't "count the links" for ranking purposes.
You'll have to look around on your own to find the MC quote, but it basically says if there's 10 links on a page and 3 are nofollow the 7 that "pass PR" will pass the same amount as they would on the same page with 10 dofollow links.
So, basically, Jerry West is giving some really bad, out-of-date (by years) advice, cause about the best internal nofollows can do is "no good", but at worst they could certainly indicate you're trying to manipulate PR and indicate your site should be scrutinized more highly or even not rank as well.
I personally think you should do what works best for your visitors, cause there's probably better things to worry about than footer links that are rather standard across the web and how they do or don't impact your rankings. My guess is having them there for your visitors could actually increase your level of trust, but I don't have any "hard fast tested proof" of that, just a hunch.
I think the biggest thing to keep in mind is: It's not all about the links and PR and hasn't been "all about the links and PR" for quite some time, but I know many people still encourage optimization Circa 2005, so the information and what to focus on can be confusing a good deal of the time.
