Shoved: Woman takes violent dislike to dedication to victim of killing

On Saturday night, Lester Chambers dedicated a cover of People Get Ready to Trayvon Martin.

Someone in the audience took exception to this, and jumped on the Hayward-Russell City Blues Festival to attack Chambers.

It's an odd gesture - regardless of whether you accept the process against Zimmerman as being just or not, the fact that Martin was shot to death is surely inarguable, and so dedicating a song to a person whose life was cut short hardly seems an act calling for immediate intervention.
