DPS is an odd bunch. The troopers follow strict protocol more than any other agency in Texas, yet at the "end" of a chase they tend to open fire with an unusual frequency. It was just about five years ago when two separate individuals were shot dead in Wise County after a chase.
But, man, they dodged a bullet (horrible pun) when a three year old wasn't killed when they fired into a car this time. This would be nationwide news if that little kid had been killed.
And the only thing the driver was wanted for at the time was speeding.
