The App Cleaning Up Crime On New Orlean Streets

The New Orleans Police Department was named the worst police force in the United States following corruption and civil rights breaches after Hurricane Katrina.

The answer for the local government was to reduce the task-force taking 500 officers off the ground and implementing a hiring freeze.

Inevitably, this only led to crime rates increasing and police response time taking over an hour.

When resident entrepreneur Sidney Torres's called on the New Orleans mayor to clean up crime, specifically in the french quarter -- the main tourist spot -- he was met with a challenge to put his money where his mouth is.

And that's exactly what Torres did.

Making use of off duty police officers and modern technology, he decided to develop an app that has inadvertently created a new model for policing.

So while it's cleaning up crime in New Orleans, it's also a great example of how we can prevent crime in other cities.
