Sending in a group of meditators at the size of the square root of 1% of a population and having it effect the entire city/state/county just because of some morals seems pretty ridiculous.
I posted the wrong link for the video (skip to 41:30):
Dr John Hagelin - The Effects of Group Meditation on Crime
We know this works, there is an overwhelming amount of published studies on this effect in peer review scientific journals, such as Yale University Journal of Conflict Resolution and all other journals reguarding Conflict resolution.

As far as the nitwits comments, acually essentially how it works is you take a world renowned quantum physicist who came up with the supersymmetric flipped SU(5) theory in phyisics, who is one of the few people in world capable of even doing math like that and have him overview studies that have an overwhelming amount of scientific verificaltion behind it. Then publish it in various journals where even the most snootious journals in the world can't even debate its verification. Then you have the Maharishi Effect.
