Charleston church marks 10 years since deadly shooting

It's been 10 years since a deadly mass shooting at the oldest Black church in the South. On June 17, 2015, a white supremacist gunned down nine people at the Mother Emanuel AME church in Charleston, South Carolina. One of them was Pastor Clementa Pinckney. CBS News' Mark Strassman spoke with Pinckney's daughter, who was 11 at the time.
