Slavery was abolished in 1865 in America but it still goes on today particularly in the Muslim world. You can see present day videos of slave auctions in Lybia And yes I believe our government was involved in 9/11. Their is several good documentaries on what the official story is nothing but a lie. The federal government basically said furniture burning brought down the towers. Their was world trade center building 7 that also collapsed that day and it was a block away from the twin towers and never was hit by a plane.
