LMPD chief launches internal investigation after video of violent confrontation surfaces

Exactly what's happened here.

"Starting in 2012, the agency sweetened Section 8 voucher payments, and pointed inner-city recipients to the far-flung counties surrounding Dallas.

Now Dallas has one of the highest murder rates in the nation, and recently had to call in state troopers to help police control it. For the first time, violent crime has shifted to the tony bedroom communities north of the city. Three suburbs that have seen the most Section 8 transfers -- Frisco, Plano and McKinney -- have suffered unprecedented spikes in rapes, assaults and break-ins, including home invasions."
