(CNN) -- Experts said Thursday that the alleged child sexual abuse scandals at Penn State University and another at The Citadel in South Carolina underscore the frailty and inconsistency of the legal system intended to protect children, while some lawmakers called for changes in reporting such crimes.





"As parents, as members of the community, as leaders of organizations, we need to ask ourselves what we can do to prevent the next Penn State," said Stop It Now!, a group that seeks to end child sexual abuse, in a commentary on its website. "Because, unfortunately, it will happen again, unless something fundamental changes."





In the Citadel case, a former cadet-turned-camp counselor faces a series of charges, including three counts of criminal sexual conduct with a minor and three counts of lewd act on a minor, according to Mount Pleasant, South Carolina, police. The school's president said this week that the university is "profoundly sorry" for not reporting allegations against the counselor in 2007.





In the Penn State case, Pennsylvania's attorney general has charged a former Penn State football coach, Jerry Sandusky, with 40 counts in what authorities allege was the sexual abuse of eight boys. In addition, two Penn State officials are charged with failing to inform police of the allegations, and questions have been raised about the university's response.





Child-welfare advocates are not alone in their calls for reform. The senior Democrat on the House Education and the Workforce Committee asked Thursday that the chairman call a hearing to determine whether federal laws intended to protect children and students should be changed.





"Potential weaknesses in specific laws designed to keep children safe have come to light in the wake of the alleged sexual crimes committed on the campuses of the Pennsylvania State University and the Citadel," wrote Rep. George Miller, D-California in his letter to Chairman John Kline, R-Minnesota. "Our inquiry should not seek to parallel, replicate, or interfere with those efforts; rather, we must examine the ongoing operation of the underlying federal laws to identify any vulnerabilities and better ensure against future risks to children."





Miller cited two federal laws: The Clery Act requires higher educational institutions to collect information about and report on crimes that occur on campus. The Child Abuse Prevention and Treatment Act requires states to develop laws mandating that child abuse be reported.





In a statement, Education and the Workforce Committee communications director Alexandra Sollberger said, "The committee is monitoring the situation at Penn State carefully and will assess the need for congressional action after the Department of Education concludes its investigation into the matter."





One state has already moved to tighten reporting requirements. Louisiana Gov. Bobby Jindal on Thursday issued an executive order requiring "all public or vocational school, community college, college or university professors, administrators, coaches and other school employees to report child abuse or neglect within 24 hours of observing an incident of child abuse or neglect." The report must be made to child welfare authorities and police.





Changes should include tightening requirements among the states about who must report suspicions that a child is being sexually abused, said Lisa Fontes, a lecturer at University Without Walls at the University of Massachusetts - Amherst and author of "Child Abuse and Culture -- Working with Diverse Families."





For example, Pennsylvania has an unusually narrow category of mandated reporters. The Department of Health and Human Services' website says that, in Pennsylvania, professionals "required to report include, but are not limited to: licensed physicians, osteopaths, medical examiners, coroners, funeral directors, dentists, optometrists, chiropractors, podiatrists, interns, nurses, or hospital personnel, Christian Science practitioners or members of the clergy; school administrators, teachers, school nurses, social services workers, daycare center workers, or any other child care or foster care workers; mental health professionals; peace officers or law enforcement officials."





"It doesn't include many people who have regular contact with children, such as school bus drivers, children's barbers, athletic coaches," said Fontes, who has a doctorate in psychology.
