Transcripts show grand jury had questions about Michael Brown's marijuana use

St. Louis police are meeting to discuss the five players from the St. Louis Rams who walked onto the field Sunday with their "hands up."

The St. Louis County Police Department maintains the Rams apologized for the gesture, which the St. Louis Police Officers Association called "offensive and inflammatory," but the team denies it issued an apology.

The players' show of solidarity has become a rallying cry for protesters who maintain Michael Brown had his hands up when he was shot by Officer Darren Wilson.

But other witnesses and Wilson maintain that was not the case.

This comes as questions are being raised about whether the marijuana in Brown's system may have contributed to how the 18-year-old may have reacted that August afternoon.
