This video, in English and Spanish, is against the death penalty in the USA.
From Dutch NOS TV:
In the US state of Oklahoma, a terminal cancer patiënt has been killed by an injection. It is a 49 year old man, convicted eleven years ago for shooting his employer.
Opponents of the death penalty call this execution senseless as the man had only half a year left to live. His lawyer had asked the supreme court to stop the execution as it would be against the constitution which bans cruel and unusual punishment.
