When Does Coincidence Become Too Coincidental?

I was browsing the news today (as I do everyday) and I found this story and this story.  They are related stories and both equally as disturbing.  In fact, the very fact that there are two stories like these stories is a large part of the thing that makes them so disturbing.

The stories discuss two separate occasions where individual's names were placed on the terrorist watch list, which includes the no-fly list.  These individuals did not find out they were on the list until they tried to get on a plane.  These individuals were not in fact terrorists and are having a lot of trouble trying to get their names cleared.  This is not the unusual part of the story; however.  It starts to get a little suspicious when it turns out that both individuals are individuals who had written criticism of the government and/or Bush Administration immediately prior to their names appearing on the list.  One of the men is a reporter for CNN who had written a piece based on an investigation of the TSA he had done.  The other man is a political author who had written a book shortly before the 2004 elections which, among other things, raised some of the questions about Bush's National Guard service.  The government claims that these are both purely coincidental and refused to comment on the suspected terrorists that supposedly go by the same names as these men.  Interestingly the men's names are James Moore and Drew Griffin.  This has also happened to some of our members of Congress, including Ted Kennedy. 

So when does a coincidence become too coincidental?  Now I fully understand there are many people who don't like Bush and who have openly criticized him and/or wrote books about his administration and there are the numerous expose type articles about the things he and his group have done.  Of course it would be extremely suspicious if they all showed up on the terror watch list (besides, it has been noted that the list is so long it is almost ineffective and adding all those opposed to Bush would make the list almost as large as the country).  So what would the criteria be to determine who goes on the list?  Maybe it is proportionate to the amount of annoyance the person caused them.  Maybe they draw from a hat.  I don't know.  Maybe it is truly a coincidence, but at what point does it start to merit an investigation?  Of the many things in the Bush administration that need investigating, is this really the one to start with? 

I guess only time will tell; however, it cannot be discounted that it is truly suspicious.
