Does the legality of Osama bin Laden's death concern you? Do you think it was an illegal act?

The international community has raised the question of whether or not bin Laden’s assassination was legal under international law. The details that have emerged suggest he was unarmed, so he could have been taken into custody rather than executed without a trial, and we did not have permission to enter Pakistan nor did we have a standing declaration of war against their country.

This has not been discussed much in the American news, so I was wondering: does the legality of this action concern you? And do you think it was legal, according to international law?
