Sounds like something Nanny Bloomberg would mandate.

A New Jersey school district is ordering all students who play soccer – and other non-contact sports – to wear helmets on the field.

The Princeton School District’s new rule is causing many parents – and even some doctors – to question whether soccer is really dangerous enough to warrant mandatory headgear to protect children from concussion.

The Times of Trenton reports that concussions and head injuries are not common among Princeton schools student athletes, but coaches and members of the school board say that doesn’t alleviate their concern.

‘We’re very aware that for players in all sports there’s a risk of head injuries and we’re just trying to do whatever we can to prevent them,’ Princeton school board president Timothy Quinn said.
