It wasn't just instinct, either. Eyewitnesses saw two (some say three) middle eastern men rushing off in a brown pickup truck. There was an APB out for the truck and the M.E. men, and it was broadcast live on the air from the television station's police scanner--that is, until everthing about M.E. men went quiet. I live nearby, and saw/heard it when it was aired the day of the bombing.
I have read different accounts of this; one report indicated that the truck was a National Car rental from DFW airport. Another account said that the license number on the brown Chevy truck was traced to a Chevy Cavalier rental car from DFW. One possibility is that the ME guys arrived at DFW, rented a Chevy Cavalier, and drove to OKC. They then used the plates from the rental car on the Chevy pickup then switched them back to the Cavalier and drove back to DFW for their return flight.
thanx for the ping.
lot of memories rekindled today.
