To deliberately burn a copy of the Koran in a public act is essentially useless. It's like throwing a Frisbee for Peace, or any of the other stupid acts of posturing practiced by the self-styled Peace Movement back during the Cold War.
It is nothing more than a Voodoo ceremony.
Islam, like all other anti-human (you know, EVIL) ideologies, can only be opposed through the education of the general population of its actual doctrines and effects, and through the consistent exercise of retaliatory force upon those Muslims who cross the line into violence.
When we do this (and we have to) the problem of Koran disposal will take care of itself.
