Brown also said the alleged motive was not "a reason or legitimate reason to do harm to anyone."

The incident marks the deadliest day for law enforcement since the September 11, 2001 terror attacks. It also drew a comparison with the November day in 1963 when a U.S. president was slaughtered by a sniper on a Dallas street only a few blocks away.
