Sam sends news that moments ago, in the middle of Police Chief David Kunkle's farewell press conference, Jack Hammack, who was standing behind Kunkle, collapsed. Those standing around him, including former Dallas Mayor Laura Miller, tried to help him up, while officers called for a defibrillator and an ambulance before administering CPR. Hammack is a former Highland Park mayor and co-founder of Safer Dallas Better Dallas with Charles Terrell. Paramedics just arrived and said he'll be fine; Sam says that amidst all the chaos at the scene, "he even cracked a joke." Laura Miller is at the podium now, wrapping up the press conference.
