If every U.S. jurisdiction had a juvenile helmet law, only 137
lives would be saved. 687 * 0.29 * (2/3) = 137

This is a phony argument. For every bicycle head injury that results in
death there are about a thousand head injuries which result in various other
problems including permanent disabilities. Do a google search on bicycle
head injury statistics and look at any of the more than 14,000 hits to get a
better idea of the real potential impact of helmet usage.
