O'Malley, who is nearing the end of his second and final term as governor,, commented on Ferguson during a weekend appearance at a Democratic picnic in New Hampshire.
O'Malley is considering a presidential run. His visit to New Hampshire was his third to the state that holds the nation's first presidential primary.
The clashes between police and protesters in Ferguson began after an unarmed black teenager was fatally shot by a white police officer. O'Malley says the situation there shows "there are gulfs and gaps and divisions and fears that separate us from one another." He says bridging those gaps is "not work that we can delegate to government."
