Nothing says, "I don't trust the NOPD" quite like military patrols.
Five subjects getting canked over a dispute concerning Narcotics, Trade of ... Does not seem to me to pass the smell test for things going completely and totally rodeo -- especially with the stated 1,375 civilian peace officers for a city that apparently numbers somewhere around 200,000.
As a comparison, Amarillo, Texas has a population of between 180,000 and 230,000 (depending on whose numbers you're looking at) and a police force of a little over 300.
Arlington, TX pop: 360,000. PD of 730.
Garland, TX pop: 217,000. PD: 390
Lubbock, TX pop: 200,000. PD: 400.
New Orleans, LA. Population, about 200,000. PD: 1,375.
Plus 300 National Guard troops. And 60 Louisiana State Police.
Granted, none of the above cities in Texas have gone through a hurricane (Beaumont, pop: 114,000. PD: 303 Hurricane: Rita) -- but Lord have mercy, 3X - 4X the number of officers for a similarly-sized Texas city and they still can't get a grip on things?
