Michael Brown's stepfather apologizes for violent rant

Michael Brown's stepfather apologized Wednesday for his angry rant the night authorities announced a grand jury's decision not to charge a white police officer for fatally shooting Brown in August.

Louis Head, however, told CNN he is being unfairly blamed for the rioting that followed his outburst, which included screaming 'burn the ----- down!" and other expletives to a crowd of protesters. Head said his "emotions got the best of me" on the night of Nov. 24 in Ferguson, Mo.

Ferguson Police Chief Tom Jackson has said authorities are trying to determine if Head's rant was an effort to incite a riot. St. Louis County Police spokesman Shawn McGuire told USA TODAY that an investigation of Head's statements was underway. He said the information will be sent to the prosecuting attorney's office, where a decision will be made whether or not to charge Head and with what crimes.
