The city that prides itself in parades rarely has a procession like this. Hundreds of police cars driving slowly with lights flashing for miles in respect of the slain officer who had only served for two years. All of those the blue lights and not one siren. Heartbreaking silence. They have come from Baton Rouge, Hattiesburg, Saraland, Satsuma and Hoover. Dallas, Texas, Escambia County, Florida and Maryland. Firefighters stand at attention in front of their firetrucks parked in the medians.
