Everything you need to know about DPS, police pursuits and why troopers shoot at vehicles

Last week, Hidalgo County District Attorney René Guerra asked the Texas Department of Public Safety to temporarily suspend its practice of using airborne snipers to fire at fleeing vehicles. Guerra made the request after DPS trooper Miguel Avila, riding in a helicopter, fired at a pickup truck he thought was carrying a drug shipment. Actually, the truck was full of immigrants suspected of entering the U.S. illegally. Two Guatemalan immigrants were killed.

One of the most difficult and controversial challenges for police officers is chasing a fleeing vehicle. Police are supposed to catch criminals. But a lot can go wrong in a high-speed chase — especially in the deadly cat-and-mouse game DPS troopers play with drug smugglers in Texas border counties.

DPS Director Mike McCraw has asked the FBI to investigate the shooting. But there are already resources available to the public that show why an incident like this near the border was probably bound to happen.

Two years ago, we found and wrote about a little-known resource: A DPS database that keeps track of every vehicle pursuit troopers are involved in. The database is available to the public through the state’s open-records law, and I teamed up with Brandi Grissom at the Texas Tribune to get a copy of the data and analyze it.

We received data for nearly 5,000 chases that occurred from January 2005 to July 2010. The database was packed with details about every DPS pursuit in Texas, showing factors like how each chase started, how it ended, and how many people were injured or killed.

One thing that jumped out at us was the high number of pursuits in Hidalgo County on the Mexican border. Between 2005 and July 2010, troopers in other Texas counties chased vehicles, on average, about 20 times. In Hidalgo County, DPS troopers chased vehicles about 30 times more often — 656 pursuits. That’s far and away the most in Texas:

Does risk of police chases outweigh benefits of capturing suspects?

I had always wanted to write a story about police chases after I watched a crazy high-speed pursuit unfold on local TV. I wondered how often these chases go bad, and how the San Antonio Police Department keeps track of that information. Law enforcement agencies usually churn out paperwork for every situation known to man. … Read more
