In a move that ethicists call fraught with conflicts and cronyism, a city council member who voted to give Berkeley Police Chief Michael Meehan a $500,000 housing loan from public funds later worked as his real estate agent and took a commission on the chief's purchase of a home, records show. Councilmember Lawrence Capitelli said he split the nearly $30,000 commission on the $1.185 million sale with another agent in his office at Red Oak Realty, where he was a partner.
