FERGUSON, Mo. (CBS ST. LOUIS) - Law enforcement in the Ferguson area are preparing for potential protests and riots following the grand jury’s decision in the Michael Brown investigation, which is expected sometime this month. Talking to “St. Louis Coptalk” forum, a supposed police officer in the Ferguson area issued a warning to others in the community to “protect” their families with firearms. Many posting in the forum expressed fears that demonstrators will take to the streets regardless of the decision made in the Aug. 9 shooting death of the 18-year-old by officer Darren Wilson.
