All MS operatives are hereby authorized to escalate measures against subject BD. His constant efforts to uncover proof of life on Mars, (something well known since the mid 70's, see the counter Viking operation report) will only hinder out efforts to heedlessly conquer Mars and then the Universe. Laugh with me here....MUAHAHAHA HAAHAHA HA.
The prefered method of assasination is a large creamy pie to the face followed by three loud honks of your standard issue clown horn. Other, similar methods may be employed at your discression.

Remember, due to extreme focus on his objective (book sales) subject cannot be distracted by accepted fact or reasoned with.
