To ward off child molesters , the city of San Mateo , Calif . , has proposed background checks and fingerprinting of Little League coaches , den mothers , and others who volunteer their time to children ( never mind , as the Wall Street Journal reports , that less than 10 percent of all child molestations take place in an institutional setting ; that most accused child molesters have no previous convictions ; and that child abuse is down in the ' 90s ) .
Child abuse and molestation had been on the raise since the 1990 's .
