Dylann Roof lawyer asks to keep evidence out of church trial

A lawyer defending the man charged in the Charleston church shootings wants a judge to keep some video and other evidence out of his federal hate crimes trial, and says explaining why in public could harm prospects of seating an impartial jury.

Dylann Roof is charged in the shootings of nine parishioners at Emanuel AME Church. The government is seeking the death penalty.

In a court filing Wednesday, Assistant U.S. Public Defender Sarah Gannett says the evidence she wants blocked includes videos, transcripts and other documents affecting Roof's constitutional rights to be free from unreasonable searches and self-incrimination.

She's asking to be allowed to file the motion supporting her request under seal, because she says making it public could affect the ability to have a fair trial.
