: Stranger things have happened. However, while we are in the
: middle of a massive government psyop on the 20th
: anniversary of another massive government psyop, I find it
: incredible that a government special ops demo expert has
: confessed to planting explosives in the World Trade Center
: before 9/11.

: Matt Agorist has the story.

: In a story that should be on the front page of every
: newspaper, or at least have any reporter worth their salt
: digging into it, a man who purports to be a controlled
: demolitions special operative for the United States, has
: come forward with a damning confession. According to Manuel
: Garcia Jr., he was tasked by a team created by Dick Cheney
: to help carry out a false flag attack on the World Trade
: Centers, otherwise known as 9/11, in order to “reshape the
: World Order to secure another century of US control.”

: According to Garcia, he’s kept this secret for the last 20
: years and has only recently decided to come clean after
: being diagnosed with a terminal illness. In his confession,
: Garcia paints a behind the scenes picture of the deep state
: at work to maintain their control through fear,
: destruction, and mass murder.

: Garcia, who holds a “Physics Ph.D. from an Ivy League
: University” says in his confession that his career began

: the Orbiting Space Laser Weapons Platform (OSLWP) project.
: According to Garcia, this program made the government’s
: work at HARP look like child’s play.

: After his work was done to allegedly construct a space laser
: weapons platform, he was approached by a former security
: guard he referred to as ‘Keith’ who was working under Dick
: Cheney’s direction to carry out a false flag attack on the
: twin towers and tower 7. In his confession, Garcia explains
