It is bureaucratically easier to fire cadets before they are sworn in.Wednesday, after learning reporters were eager to ask him about the fire cadets, Turner hastily cancelled his regularly scheduled news conference. He didn't respond to a question asked by ABC13's Ted Oberg."Mayor, do you have a minute to talk about the firefighters not graduating?"Turner walked about the council chamber without answering.The 44 cadets group recently practiced their firefighter's oath with Houston Professional Firefighters Association President Marty Lancton.
