Governor Pataki yesterday took to the skies yesterday to push for tougher laws against sexual predators.  He flew to Buffalo, Rochester and Syracuse, holding airport press conferences urging the Assembly to act on a five-point plan he is pushing.  When those who stalk and rape a child can be out on the streets in two or three years,when 5,000 sexually violent predators are currently awaiting release from our state prisons, we owe it to the families across New York to waste no more time and to enact these measures now, Pataki said.
