Here's why we mark Night Out Against Crime in October, unlike most of the United States

In most of the United States, the National Night Out Against Crime is on the first Tuesday in August. But August daily temperatures in New Orleans average 84.7 degrees, so local police decided some years ago to move their events to a cooler time of year.

This year, it's Oct. 4, so law enforcement agencies across the region are encouraging neighbors to host block parties and cookouts, or at least sit outside with porch lights on, on Tuesday night. Many of the agencies plan to send officers and equipment to the events. 

To generate more interest, at least seven agencies are getting an early start, with a free public celebration Sunday from noon to 6 p.m. at the Pontchartrain Center in Kenner. Two bands, the Topcats and Karma, will play, and first responders will show off their SWAT vehicles, canine units, motorcycles and rescue equipment.

The National Night Out Against Crime began in 1984, when the National Association of Town Watch introduced it as a way to improve relations between residents and law enforcers. Over time, it has grown from small gatherings on porches to a larger demonstration of neighborhood camaraderie, the association says.

"Programs like these empower you to take a stand against crime and to help others do the same,” said Kenner Police Chief Keith Conley, who invited residents to organize their own events Tuesday night.

Gretna police said they are sponsoring an event Tuesday night at Mel Ott Park, with free food and drinks, games for kids, music by Ryan Foret and Foret Tradition and a display of police equipment.

"This will be a fun evening for you and your family and give you the opportunity to get to know your Police Department – we hope to see you there," says a post on Gretna police Facebook page.
