Ed Formanek has shown me how to reduce this question to proving that B(n)/g(2,P(n)) is torsion free, where B(n) is the braid group, P(n) is the pure braid group and g(2,G) is the second term in the lower series of G. Joan Dyer's proof that B(n) is torsion free doesn't seem to extend to this case. Thanks, Marcelo Aguiar Cornell University
