    Law Enforcement Memorial

    SObanner

    To lose an officer is to lose a hero.

    Law enforcement officers dedicate not only their careers, but their entire lives to bringing peace and justice to our society - a blessing that can never be repaid. It is a particularly inexplicable loss when an officer is killed in the line of duty.

    The Tarrant County Law Enforcement Memorial remembers these officers, their stories and their service.
