Government labs continue to withhold data from experiments performed at their facilities

If you have read my book, you know that one of my biggest complaints about government conducted research on cancer is the amount of time before this research is made public.
I recently had a conversation with yet another researcher who has waited years for his employer to allow him to publish his results.  These are the hurdles he must jump at his facility:
1.) Perform the research
2.) Submit the publication to his department head
3.) Remind his department head every few weeks that he has submitted research for his approval
4.) The department head picks 3 other department heads to give opinions on the work
5.) Two months later the opinions are returned to the researcher suggesting additional experiments.
6.) The frustrated researcher begins the process again.
7.) If the internal reviewers are satisfied, he can then submit his paper for the appropriate research journal (which must be externally reviewed).

I think the same thing is happening at this facility as at the one I once worked for.  The administrators are so concerned with the political ramifications of publishing research that is incorrect or unpopular that they would rather withhold the work until it is obsolete.
I continue to hear stories of how the same thing is happening at different branches of the government cancer research entity. It appears that the amount of cancer research that is sitting around at these facilities cost millions if not billions of dollars and they are being wasted by the corrupt politicians who head these laboratories.
I want some of my tax money back....
