Summary: In Texas, seven people were killed and 22 wounded in Odessa during a mass shooting Saturday. After state troopers stopped the alleged gunman for driving his car erratically, he shot one of them and then sped away, firing at people randomly. The massacre comes less than a month after one in El Paso left 22 dead. William Brangham talks to Mitch Borden of Marfa Public Radio for the latest updates.
