Jamaican reggae singer Buju Banton is asking for a shorter prison sentence. In court documents filed yesterday, Banton’s attorney, David Markus, says a 15-year-sentence is “way more than necessary” in Banton’s case.

The Grammy winner was convicted in February of conspiring to set up a cocaine deal in Florida in 2009. He faces a mandatory minimum of 15 years in prison at his sentencing hearing June 23 in Tampa federal court.

Markus argues that Banton's limited participation in the drug buy, his charitable work in Jamaica and his otherwise clean record entitled the singer to a reduced sentence. In the same documents Banton also seeks an acquittal and a new trial.

The documents also included letters of support for Banton from actor Danny Glover, reggae singer Stephen Marley and Atlanta Hawks basketball player Etan Thomas.
