I'm confused as to what you're unhappy about and who you're blaming for this outcome. Some courageous soldiers attempted to get an elusive mass murderer and bring him to justice. During the attempt there was a firefight and he was killed in the exchange.
It is obvious that this outcome is upsetting for a lot of people, but not for the same reasons than yours. This man caused a lot of griefs to many families, not only in the U.S., but also throughout places in the world where Al Qaeda has stricken, (including Afghanistan). Some scars are still not completely healed.
Those words, "His demise should be welcome by all who believe in peace and human dignity", simply serve as solace for the fact that they were unable to take him alive.
Now, turning this into an Obama thing is your own prerogative. Was he taking credit/responsibility in the video? To some extent certainly, but I didn't perceived him trying to play with people's emotions.
