Ashamed what happened to Osama ?

Why in the world would peace loving Democrats allow Osama and others in the compound to endure such a hellish way to die? I am so ashamed that justice was not allowed. Osama should have been brought back to the United States to stand trial. Aren't people innocent until proven guilty? If he were found guilty, then he could have been put in prison! Killing is so wrong! What happened to forgiveness? I think President Obama set a terrible example, especially since he has spoken about compassion and world peace!
