Nah, lots of us want proof on both counts.

As a significant comment on the pertinent article - they claim that a
helmet seems to save some 15% of youth fatalities.

An important distinction - they say this about *helmet laws*, not
helmets. The actual effect for helmets themselves may be higher if we
account for noncompliance, which may be substantial in this case (or
not, but still the distinction needs to be made).

In other words, requiring kids to wear helmets does not mean every one
of them will. This study appears to be examining the effect of the
legislation, which can only approach and never exceed the effect that
would be attained by perfect compliance.
