Why was this POS released on bail?

Richmond Times-Dispatch: Man whose truck hit trooper is arrested again:

An Abingdon man who was charged with drunken driving after his pickup struck a state trooper Friday night in Smyth County was arrested again yesterday morning, on charges of intoxication in public and possession of drugs, state police said.

Barry Dean Marshall II was a passenger in a car that was pulled over at 2:17 a.m. by a Chilhowie police officer.

The officer saw the vehicle along northbound Interstate 81 at the 36-mile marker, according to the arrest warrant. Chilhowie is a Smyth County town about 30 miles northeast of Bristol.

Chilhowie police arrested Traci Tashona Peake, 21, on a charge of driving under the influence.

As part of the same incident, Smyth deputies assisting in the stop arrested Marshall, 32. He was charged with public intoxication and possession of drugs with the intent to manufacture or sell, according to the arrest warrant.

Marshall had been charged Friday night with driving under the influence after a pickup he was driving struck trooper K.S. Chapman on I-81, a few miles from where Marshall was arrested yesterday, Conroy said.

Chapman, who has been with the state police for five years, was listed Saturday in critical condition at Bristol Regional Medical Center. State police and hospital officials declined yesterday to release an update on his condition.

Conroy said Chapman’s family requested that his medical record remain private but he said he believes Chapman’s condition has not worsened.
