NEW HAVEN >> A passionate crowd filled City Hall chambers Thursday night to participate in a public hearing concerning how to revamp the Civilian Review Board, the go-to panel for residents who believe they've been mistreated by police.Testimony from residents including Emma Jones, whose son Malik was killed in the city in 1997 by an East Haven police officer following a pursuit, focused largely upon the same demands: the next edition of the Civilian Review Board must have more authority, including the power to issue subpoenas.
