The U.S. Supreme Court will hear arguments next week on the most divisive immigration law in recent memory. Arizona's Legislature passed SB 1070 two years ago, but much of it has been put on hold pending the court's decision.

In 2009, prosecutors in Detroit discovered more than 11,000 boxes of potential evidence in rape cases left completely unprocessed. Row upon row of what are called "rape kits" remained untouched on shelves in a police evidence room for years.

Since then, Wayne County prosecutor Kym Worthy has lead the effort to sort through those 11,000 rape kits and to find the funding to get them processed.

Charles Colson, who served time in prison for his role in the Watergate scandal and later became an influential evangelical Christian, has died. Colson went from being one of the nation's most despised men to a hero of conservative Christians.
