Al Capone's prized gun and other possessions are going up for auction but ex-prosecutor condemns "blood money" profits

He ruled the streets of Chicago through fear during most of the Prohibition era. Now, nearly 75 years after the death of the gangster Al Capone, some of his most prized possessions are up for sale.

This Friday, Capone's surviving granddaughters, helped by Witherell's auction house in California, will sell everything from weapons to watches and jewelry.

"We have lived all our lives, my sisters and I, being very quiet about the family, and not talking about our personal stories," Diane Capone told CBS News' Lee Cowan.
