Sean Ryan of Jamaica Plain, who ran for an at-large city council seat last year, said today he is running for the District 6 seat being vacated by John tobin.

Ryan, a Boston public-school teacher, said he will make education the focus of his campaign. At an at-large candidate debate last year, he called for an end to school busing, an increase in the number of charter schools and a 10% pay cut for all city workers.

Also last year, Ryan blamed the Federal Reserve for 9/11.
