Former N.Y. cop, Bernard Kerik, leaves Taser board

SCOTTSDALE, Ariz. - Former New York police commissioner Bernard Kerik is stepping down as a director on the embattled stun gun maker Taser International Inc.'s corporate board, the company announced Monday.

He will be replaced by former Montana Gov. Judy Martz.

Taser itself is under federal and state scrutiny over the safety of its stun guns and accounting issues. The Securities and Exchange Commission is also conducting an informal probe into Taser's safety claims. The company maintains that the guns are safe.
