(CNN) -- Phillip Garrido was registered as a sex offender, regularly visited by parole officers and fitted with an ankle bracelet to track his movements -- but nothing prevented him from being around children, according to a victims' advocacy group.



Phillip Garrido, a registered sex offender, was arraigned in California on Friday.



Garrido is charged with kidnapping Jaycee Lee Dugard in 1991, when she was 11, and raping her over the course of years.



Police say Dugard lived in a huddle of tents and outbuildings hidden behind Garrido's home, and gave birth to two daughters, now 11 and 15, fathered by Garrido.



Garrido and his wife Nancy were arrested last week. Both have pleaded not guilty.



"Here we have a guy who is essentially under every kind of supervision we allow. Law enforcement had every tool available to them, and [the tools] failed," said Robert Coombs, spokesman for the California Coalition Against Sexual Assault.



Gordon Hinkle, spokesman for the state Department of Corrections and Rehabilitation, said a parole officer visited Garrido at his home, sometimes unannounced, twice a month. Garrido was also required to go to the agent's office once or twice a month, Hinkle said.



Garrido wore a GPS anklet, and his movements were tracked passively, Hinkle said, meaning parole officers checked his location after the fact, as opposed to active monitoring, which involves watching parolees' comings and goings in real time.



Despite the tight supervision, Garrido "was technically allowed to be around minors," Coombs said, because his parole stemmed from the November 1976 rape of Katie Callaway Hall, who was 25 at the time of the assault.



He was sentenced in 1977 to 50 years at the federal penitentiary in Leavenworth, Kansas, for kidnapping, because he abducted Hall in California and transported her across the state line to Reno, Nevada, where he raped her in a warehouse, according to court documents. A Nevada court separately sentenced him to five years to life for the rape conviction, the Reno Gazette-Journal reported.



While in prison in 1978, Garrido sent a handwritten letter to Judge Bruce R. Thompson, saying he was recovering from seven years of LSD use and progressing well.



"I am so ashamed of my past. But my future is now in controle [sic]," he wrote.



Court documents show Garrido requested that his 50-year sentence be reduced to 25, making him eligible for parole in eight years, "where he could be released to the state of Nevada as an educated person and being a rehabilitated person."



According to a 1978 court transcript, attorney Willard Van Hazel Jr. told a judge, "Without the influence of any of this drug involvement, I think Mr. Garrido would pause before carrying out sexual fantasies."



After more than a decade at Leavenworth, Garrido received a federal parole but was sent to Carson City, Nevada, in January 1988 to serve his rape sentence. However, according to the Reno Gazette-Journal, he was automatically eligible for state parole because of the time served in federal prison.



The Nevada Offender Tracking Information System indicates he appeared four times before the parole board, which granted his request in August 1988, about 11 years after he was incarcerated.



He moved to Antioch, California.  Three years later, 11-year-old Dugard was abducted from her home in South Lake Tahoe, California, about 100 miles northeast.



"He served about 20 percent of his sentence, and it doesn't take a mathematician to figure out if he served only one-third of his sentence, Jaycee Dugard doesn't end up in the predicament that she's in," said Andy Kahan, a crime victims' advocate in Houston, Texas.



Citing revised federal sentencing guidelines, Kahan and Illinois defense attorney Stephen Komie concur that this is not something that could happen today.



"If he got 50 years, say, he would have 600 months. He would only get 50 months off. He would do 550 months," Komie said. "So this would not be repeated in the
