Teen who ran over 6 cyclists outside Houston walks free
Authorities are tight-lipped about whether or not the teenager would face any charges after the fact.
It is not clear why the teenager was not immediately arrested. Representatives at the Waller County District Attorney's Office did not answer questions about the case but instead referred to a Facebook post saying it is still under investigation by police.

Death of Sandra Bland
Sandra Bland was a 28-year-old African-American woman who was found hanged in a jail cell in Waller County, Texas, on July 13, 2015, three days after being arrested during a pretextual traffic stop.[1][2] Her death was ruled a suicide. It was followed by protests against her arrest, disputing the cause of death and alleging racial violence against her.[3][4]

Bland was pulled over for a minor traffic violation on July 10 by State Trooper Brian Encinia. The exchange escalated, resulting in Bland's arrest and a charge of assaulting a police officer. The arrest was partially recorded by Encinia's dashcam, a bystander's cell phone, and Bland's own cell phone. After authorities reviewed the dashcam footage, Encinia was placed on administrative leave for failing to follow proper traffic stop procedures.[5][6]
