Osama Bin Laden Killed in 2011, Why Did Benazir Bhutto Say He Was Murdered in 2007?

Osama Bin Laden was allegedly killed by US military on 2nd May 2011

However, 4 years previously, in 2007, respected British journalist David Frost interviewed ex-Pakistan prime minister Benazir Bhutto for Al Jazeera when she mentioned:

"Omar Sheikh, the man who murdered Osama Bin Laden"

Funnily enough Benazir Bhutto was assassinated later that year in December 2007…….
