Regardless e-mails are the wrong way for governmental information to be conveyed as they can easily be hacked into (which is an irony since the internet was based on a means of communication used by the military). Since an email that was discovered showed that there was a cover up on one side as regards global warming, if any email is found to show any kind of unethical or illegal behavior then that would have to be investigated on either side. Investigating a political cover up was what unseated Richard Nixon and regardless even if Bush is not in power, much of his former administration is as well as other political and military advisors and people who are influential within the military industrial complex are. Naturally, if the emails would compromise the safety of American troops or America as a whole that would be different though.
I think it really does not matter at this point and we have enuff on our plates as it is these days. If we knew what really goes on behind closed doors of any administration or gave it the scrutiny that we do give these days, we would be horrified im sure. Bush in my book is no better or worse than any of the others. No, I dont think they should be made public and last I heard the verdict is still out on if anything is missing or not. IMO
