It appears to me that the helmet pictured above cracked.

Helmets are supposed to compress; I can't tell from the pics whether this one did.

With the negligible amount of tensile strength of helmets, no significant amount of energy is dissipated by it cracking.

Aside from this, the hyperbole which rolls in, while amusing to some degree, only reflects the ignorance of the subject on the part of the writer.

There is no doubt that helmets can help prevent or reduce certain injuries.

That they have 'life saving' cababilities is absurd.
