Silenced Scientist..... For National Security reasons??

I've been reading a couple reports that are saying that Homeland Security officials are confiscating 'real scientists' collections and documentations of the oil disaster in the Gulf of Mexico because they will not sign a legal confidentiality document.   They confiscate this stuff on the grounds of National Security..

This made me question, what is 'National Security' protecting; the People in the nation, or BP and corruption??

Why do we have all these things causing problems and they use 'for national security reasons' you can't have/go/do what normally you could have/go/do.

We have had more than a million tar balls washing ashore in a community and a Gulf that has been declared oil/tar free from government officials IN CHARGE and by BP. This is a complete lie and I can prove it by many photos by gregg hall on facebook:

NPR did a story on this and a caller called in telling the story of the confiscation taking place by the Homeland Security Forces for the reason of national security:

The top link you can listen to the story on NPR and the bottom link you can just read the caller who called in and what he said they did to him.

Of course, there is no news about any of this on MSM, at all!!
