DALLAS (Reuters) - The Dallas police chief said on Monday that Texas state laws allowing civilians to carry firearms openly, as some did during the protest where five officers were fatally shot, presented a rising challenge to law enforcement, as he stepped into America's fierce debate over gun rights.
Dallas Police Chief David Brown, during a news conference, also gave new details about his department's use of a bomb-carrying robot to kill Micah Johnson, the 25-year-old former U.S. Army reservist who carried out the sniper attack that also wounded nine other officers last Thursday.
