The Austin Fire Department is dealing with a public image problem involving firefighters accused of viewing pornography while on duty. Two firefighters have been suspended over it. And as many as three dozen more are under investigation for what's called, suspicious use of the internet.

A city memo released Tuesday sites 21 different instances in which Firefighter Arturo Martin viewed pornography while on duty at a Northwest Austin fire station. The memo shows that Martin admitted to visiting pornographic websites. Since Martin admitted to the violation, acting Chief Jim Evans decided to suspend him for 90 days.

Chief Evans also suspended firefighter Daniel Martinez for four days for lying about how many times he viewed a pornographic e-mail while on duty.

Many more suspensions could follow. Routine maintenance of a computer at one fire station uncovered what the department is calling, questionable internet usage involving 12 to 36 firefighters. After first refusing to do any on camera interviews with KVUE, AFD allowed an assistant chief to answer our questions.

"The chief was very disappointed. We put these policies into effect. We have the trust of the public. They invite us into their homes and for one of our firefighters through his actions to call that into question disappoints the chief greatly," Assistant Chief Dawn Clopton said.

Clopton said the chief instructed every captain to reiterate the internet policy and the possible punishment to every firefighter at every fire station in the city.

"Ensure that no one thinks this is something they can do and get away with. Make sure there are no misunderstandings on his position that as these come to light they're going to be investigated, they're going to be dealt with, they're going to be punished if that's the appropriate end to the investigation," Clopton said.

This investigation comes on the heels of firefighter Lt. Christopher Giberson's firing in June. He's accused of viewing and showing pornographic images to firefighters as well as sexual harassment. He is now appealing.

It's the public's image of the Austin Fire Department that Clopton is most concerned about.

"I don't care what people do on their private time but if they're on the clock and they're working for the citizens, then I don't think they should be spending their time searching the net much less looking at porn," said Lisa Stevens, taxpayer.

"That's my taxes. I don't want my taxes paying for WIFI for that," said Nancy Sue Ellyson, taxpayer.

In March 2007, city officials sent a memo to all City of Austin employees explaining that viewing pornography on city computers is a severe violation of policy. In April 2007, then Fire Chief J.J. Adame reiterated that any employee caught viewing pornography could be fired.
