While they present reasonable objections to the utilitarian as well as the justice defence of such legislation, their review of the empirical evidence contains inaccuracies, omissions and a bias in the selection of empirical data. While there are legitimate reasons to argue against mandating helmet legislation, these arguments should still be based on clinically and scientifically sound evidence.
