According to numbers being put forward by Homeland Security in sex-predator stings going back three years - 85% of those captured for these crimes - were illegal aliens.

Homeland Security has arrested upwards of 9000 illegals for sex-predator crimes through an on-going procedure called "Operation Predator."

The program was designed to safeguard children from foreign national pedophiles, human traffickers and international sex tourists, and in the first year alone, ICE arrested more than 3,200 child predators in the U.S. who committed forms of child exploitation.

Two samples:

In fact, ICE reported a twice-deported child molester from Mexico was arrested with 25 pounds of marijuana and eight firearms in his possession in May 2004. "Nicolas Sandoval-Medina" first entered the U.S. illegally in 1996 and was deported to Mexico in July 1997. He later re-entered the country illegally and had sex with a 12-year-old girl in a Des Moines motel room, and was subsequently convicted on two counts of Lascivious Acts with a Child in December 1999. He was also criminally prosecuted for re-entering the country after deportation, a felony, and was deported to Mexico again in July 2000.

In another case, an illegal immigrant from Mexico who attempted to abduct a 7-year-old girl from a laundromat was one of 25 arrested in a sting targeting criminal alien sex offenders in Los Angeles last August. Four of the offenders, two Salvadorans, a Honduran and a Mexican, previously had been deported from the U.S. A fifth man, Alejandro Rodriguez Villegas, 50, convicted of lewd and lascivious acts on a child under 14, also faces criminal charges but remains on the loose.
