Perhaps they can promote themselves by selling custom monogrammed loud whistles that people can take with them to protest marches, etc. That way we can all be "whistleblowers!" Something like those from this site, which seem rather cheap. I might add it to my Cafepress.com site, but it wouldn't be as easy to manage that as other products they sell that don't take any time and effort... Perhaps someone else out there already has a site to sell these sort of things? I'd link to it from my cafepress page.
