Steve Chapman: Helmet laws make absolutely no sense

If you have a strong disregard for your own health and safety, you are free to express it in all sorts of ways. You can smoke cigarettes. You can gorge on fast food five times a day. You can go live among bears in Alaska.

You can stagger through the worst part of town at 2 a.m. You can become a trapeze artist. You can join the Marine Corps. But if federal regulators get their way, you will not be able to ride a motorcycle without a helmet.
