ORANGE COUNTY, Fla. -- Orange County deputies have used their Tasers 2,650 times over the last seven years and, despite numerous complaints, not one time has a deputy been disciplined for misusing the weapon.

Eyewitness News has learned that is just one aspect of a federal review of the Orange County Sheriff's Office use of Tasers. The Department of Justice is in Central Florida looking into the agency's use and policies involving Tasers.

DOJ investigators are looking through each Taser use. Every time a deputy fires a Taser, the DOJ wants to know why and if it was justified.

Three and half years later, Damion Johnson still has scars after being stunned several times by the Orange County Sheriff's Office. He was at the corner of Parramore and South when a couple of deputies approached him and wanted him to spit something out of his mouth. He refused.

"They figure, if they tase me, he won't be able to swallow, so he'll be able to cough it up," Johnson explained.

In 2004, there were 35 incidents where deputies used a Taser when a person did not comply, but then, in 2005, the policy changed. Deputies were instructed that they could no longer use a Taser on an unarmed person simply because they don't comply with commands.

Even with the stricter rules, suspects are still complaining about Taser misuse. Johnson has filed a lawsuit against the sheriff's office in federal court.

"They violated his constitutional right by torturing him to get drugs out of his mouth," said attorney Thomas Luka.

Channel 9 has learned, the DOJ is focusing its investigation on whether or not deputies are complying with the new policy, if there is excessive use or misuse.

The sheriff's office reports, since 2000, the Taser has been used about 2,650 times. In every internal investigation, every deputy was cleared of any complaints and found to have used the Taser within department guidelines.

Even so, the DOJ is reviewing all of the files to make its own determination.

"What we know and what we believe at this point, the Orange County Sheriff's Office policy is appropriate and we believe that will be the outcome of the investigation," said Cpt. Mark Strobridge, Orange County Sheriff's Office.

Sources also told Channel 9 there are at least six DOJ investigators and two U.S. Attorney's working the case from both Washington DC, as well as Florida. It is also the first DOJ Taser investigation ever in the United States.
