The BM Bombing Boat Note

According to the authorities, the surviving Tsarnaev brother wrote this "confession" while hiding in the boat:

This reminds me of a similar picture from 50 years ago:

Just as the "Oswald with a rifle" photos helped persuade the public that he was indeed the assassin of JFK, the boat note and the alleged carjacking confession are helping to persuade the public that the Tsarnaev brothers were indeed the Boston Marathon bombers.

Are these items genuine or are they fakes staged to frame the patsies?

Who you gonna trust? The FBI?
