"Leaving Earth is one of the best and certainly the most comprehensive summary of our drive into space that I have ever read. It will be invaluable to future scholars because it will tell them how the next chapter of human history opened." -- Arthur C. Clarke

Homeland Security settles lawsuit of reporter whose home they illegally searched

In a lawsuit settlement Homeland Security has agreed to pay $50,000 and promise to return everything they seized — including confidential files and paperwork that identified Homeland Security whistleblowers –during an illegal raid of a reporter’s home.

Audrey Hudson, an award-winning journalist most recently at the Washington Times, told The Daily Signal she was awoken by her barking dog around 4:30 a.m. on Aug. 6, 2013, to discover armed government agents had descended on her property under the cover of darkness. The agents had a search warrant for her husband’s firearms. As they scoured the home, Hudson was read her Miranda rights.

While inside Hudson’s house, a U.S. Coast Guard agent confiscated documents that contained “confidential notes, draft articles, and other newsgathering materials” that Hudson never intended for anyone else to see. The documents included the identities of whistleblowers at the Department of Homeland Security. The Coast Guard is part of Homeland Security.

The settlement requires the government to return all documents, destroy all notes made from these papers, and promise it did not copy anything. Does anyone believe this?

Pioneer cover

From the press release: From the moment he is handed a possibility of making the first alien contact, Saunders Maxwell decides he will do it, even if doing so takes him through hell and back.

Unfortunately, that is exactly where that journey takes him.

The vision that Zimmerman paints of vibrant human colonies on the Moon, Mars, the asteroids, and beyond, indomitably fighting the harsh lifeless environment of space to build new societies, captures perfectly the emerging space race we see today.

He also captures in Pioneer the heart of the human spirit, willing to push forward no matter the odds, no matter the cost. It is that spirit that will make the exploration of the heavens possible, forever, into the never-ending future.

    Where is the accountability? It seems nobody of consequence that works for the government ever goes to jail for anything wrong they do. Including the police. Equality of rule under law is necessary for the Republic to function properly but the system has become corrupt and twisted beyond reason.

    As long as they “promise” and don’t cross their fingers.

    They should have asked for $50 million! The agents involved in the raid should be fired and the managers who arranged this raid should be jailed.
    More criminal activity from the organized crime unit known as the democrat party.

    listening to the radio last night I heard someone (Craig Hulet) and he said something that I thought was prescient or relevant, his comment was that our government is no longer “ours” (the peoples) its “theirs” (international corporations). And international corporations have no loyalty to country but loyalty to profit.

    Why else does Obama speak against wealth and encourage its redistribution but spends all of his time pandering to that wealth to raise money and that wealth has increased and has not been diminished? This is not an indictment of capitalism but the indicator that it has been perverted and has been pushed too far to one end of the spectrum because the government that is tasked with its reasonable regulation has been back doored with money by those same corporations. Look at what Obama (and all of the rest of them) does and not what he/they say.

    I find that to be true enough, just as much as we are also possessed by the left and the combination of the two have resulted in what we have today, chaos and blatant, raw and naked, irrefutable incompetence which is an existential threat to “us”, WE THE PEOPLE.

    PS: People are coming to the conclusion that everything that the government says is in fact a lie and more a function of politics than truth. And they are correct, the governments priority is not the truth but to manage the “truth” in order to retain power. It is reasonable to assume they are lying, that should always be the peoples default position until they can reasonably establish the truth to the best of their ability.

    Immigration, ebola, the economy, unemployment etc, etc, etc, all massaged and tailored “truth”.

    “A search warrant for her husband’s weapons.” Wow, unless it states specifically that they can take her professional and confidential notes, then it’s a no go. Reporter should have sued for a lot more.
