Proposition P on next week’s Los Angeles County ballot would raise money for parks, recreation, gang prevention, protection of beaches and maintenance of zoos and museums. It would replace Proposition A, passed in 1992, which runs out next year. But it was drafted behind closed doors and placed on the ballot at the last minute, without any public discussion. Supervisors Antonovich and Ridley-Thomas voted against it. But support came from Gloria Molina, Don Knabe and Zev Yaroslavsky.
