The Texas Tribune and the San Antonio Express News teamed up to analyze nearly 5,000 high-speed chases by DPS troopers. "Statewide, DPS chases resulted in 1,300 accidents, 780 injuries to troopers, other officers, suspects and bystanders, 28 deaths and an estimated $8.4 million in property damage in the last five years." What's more, "Nearly 13 percent of the chases — 656 — happened in Hidalgo County. Of the 10 counties with the most chases, five were counties along the Texas-Mexico border."
One notable observation: "The analysis also reveals that troopers use aggressive pursuit tactics — including firing guns and setting up roadblocks — that many other law enforcement agencies prohibit. One expert says that DPS policies allow troopers to take too many risks, endangering the lives of officers and bystanders. 'They’re crazy,' says Geoffrey Alpert, a professor at the University of South Carolina, who has studied pursuits at police departments across the country."
Another remarkable tidbit: "The pursuits didn’t always end with fleeing motorists in handcuffs, though. The suspects in about 40 percent of chases in Hidalgo County escaped on foot — or swam away to Mexico — eluding officers and often leaving behind loads of marijuana and narcotics in vehicles mangled in accidents and sometimes submerged in the Rio Grande. Statewide, more than 30 percent of all DPS chases ended with the suspect eluding officers on foot. Fewer than a quarter of all suspects, both statewide and in Hidalgo County, stopped and surrendered."
I would not have guessed that the number of chases ending with the suspect successfully eluding troopers on foot would have been so high, nor that the proportion who stop and surrender would be so low.
