And from the biography it states " Craig worked for the Purex Corporation before joining the Dallas Police Department in 1959. He was named Man of the Year by the sheriff's office in 1960 for his work in aid in helping to capture an international jewel chief. He had a successful career in the DPD and was promoted four times".
The Spartacus biography is wrong.
He was hired as a Dallas County Deputy Sheriff.
He was never a local city Dallas Police officer
From the Shaw trial....
Q: Mr. Craig, where do you reside?
A: Dallas, Texas.
Q: Were you residing in Dallas, Texas on November 22, '63?
A: Yes, sir, I was.
Q: On that occasion by whom were you employed?
A: Sheriff Bill Decker.
Q: Were you a Sheriff's Deputy on that occasion?
A: Yes, sir, I was.
Q: How long had you been a Sheriff's Deputy on November 22, 1963?
A: Four years.
However...as has been demonstrated completely by now...there was gross collusion between the city cops and the Sheriff's Dept.
