SAN DIEGO -- A sexually violent predator about to be released back into society spoke to 10News about why he feels he'll never re-offend.

"I used children for sexual gratification," said the man, who agreed to the 10News interview if he could be called "Bob" instead of his real name.

Bob told 10News, "I was a coach and teacher for about 22 years."

He was a child molester for 15 of those years, and was a trusted member of his community. He said he used his position to coerce teenage boys into sex acts.

"I was arrested in 1987, and started serving prison time in 1989," said Bob.

He served nine years in prison, and then another 11 years in treatment at Coalinga State Hospital.

"If that isn't the most intensive program, I don't know what is," said Bob.

He said he wants people to know why he's no longer a threat to the community.

"I'm no longer that 39-year-old that was arrested. I had a long history of sexual abuse, and I'm almost 62 years old. My libido is a fraction of what it used to be. We want the community to know that we've been challenged with intense therapy. If anyone is ready to enter the community, we are. If we make a mistake, they're going to revoke us," said Bob.

A mistake is what sexually violent predator John Norman made after a court released him to San Diego County, even though he did not finish the state's treatment program.

Bob said that gives the public the wrong impression.

"Some judges have let out a couple men who had not finished the program. It's not fair," said Bob.

Bob said releasing Norman wasn't fair to the program, nor to the community of Boulevard where Norman was placed.

Bob said he isn't looking for sympathy and knows his life outside of the institution will be under a huge magnifying glass.

"Gaining trust is going to be a very hard thing. It's not something that I expect from the community. I have to work and gain that trust," said Bob.

Bob has been undergoing intensive treatment. Years of counseling have now led to testing, where he looks at pictures of children. While doctors ensure he is not aroused, he takes lie detector tests to further prove he is not attracted to kids any longer.

It is the same program that convicted sex offender Matthew Hedge has been through while the court considers placing him back in San Diego County in the next few weeks.

While Hedge would not talk, Bob said the patients who have completed the program are ready for release.

"I feel I'm ready. If I wasn't, I don't think I would want to go out because I do not wish to end up … my next bad step is a lifetime commitment in prison," said Bob.

There is one more thing Bob wants people to know about sexually violent predators.

"It's very, very difficult to pinpoint a pedophile. But to protect your child, always understand why an adult would want to be around your child, for what reason," said Bob.

Even if they are a coach or school teacher.

Bob is not from San Diego, so he will not be released in the county.

However, Hedge could be released to live in the county by April.
