Bradley Manning is an Army private who as an act of conscience released government documents aimed at exposing misconduct in the wars in Iraq, Afghhanistan, as well as hypocrisy in U.S. foreign policy. He was just sentenced to 35 years behind bars (with a chance for parole in about 10-ish years.)
Hosni Mubarak is a corrupt former dictator of Egypt who controlled a torture-happy security force and who is responsible for the deaths of scores of protesters in a futile bid to hold onto power in 2011 He is now free to move about the country.
So I guess there is justice in the world. It's just not good justice, or fair justice.
