Six law enforcement officers involved in a narcotics training course refused to be interviewed by state investigators examining allegations that at least one officer gave marijuana to an Occupy protester to see how he would behave.
Records of the now-closed investigation, obtained by the Star Tribune under the Minnesota Data Practices Act, reveal another factor in Hennepin County Attorney Mike Freeman's decision in September not to prosecute officers involved in the State Patrol's Drug Recognition Evaluation program, which trains officers to recognize the symptoms of drug impairment.
The program was suspended after allegations four months ago that some officers provided marijuana to people they found in Minneapolis, including Occupy protesters on Peavey Plaza.
After the Bureau of Criminal Apprehension (BCA) concluded its investigation, Freeman announced in September that there was "insufficient evidence to file criminal charges" because of contradictory statements by witnesses.
But unlike the 2010 investigation of the scandal-plagued Metro Gang Strike Force, in which Freeman blamed officers for keeping silent, he did not make note of it in this case.
Freeman spokesman Chuck Laszewski said the officers' refusal to be interviewed "was only one factor and not necessarily the biggest factor" in the decision on charges.
"This is no different than many of the gang cases we have where the gang members won't testify," he said. "In those type of cases and in this particular case we can only charge and bring a case to a jury where we have sufficient admissible evidence."
Chuck Samuelson, executive director of the American Civil Liberties Union of Minnesota, a persistent critic of police misconduct, defended the right of officers to refuse to talk.
