There is no surer bet than that legal gambling on sports will grow exponentially over the next several years following the Supreme Court’s ruling in June that a federal law barring it was unconstitutional.

The vast expansion of gambling pose risks to the integrity of college and professional sports, and raise the question of how such gambling will be marketed, especially to kids who spend a great deal of time online.

Sports gambling regulation so far has fallen to the various state agencies that regulate other types of gambling within their borders. In Pennsylvania it is the state Gaming Control Board.

Recently, the U.S. House Judiciary Committee conducted a hearing on whether federal regulation is needed to oversee sports gambling, which inevitably is conducted across state and even international borders.

Professional sports leagues are concerned. They want 1 percent of the take to ensure the integrity of their games, which is ridiculous. They bear that burden regardless of whether gambling is legal, illegal or both. Ensuring the integrity of games is part of their cost of doing business at all times.

The biggest question, and the one that Congress should tackle, is marketing to kids. Gambling is highly addictive, like tobacco and drugs, and Congress should approach the matter accordingly — establishing strict rules and penalties that preclude use of the Internet to market sports gambling to anyone younger than 21.

Congress should strive to confine sports gambling to adults.

The arc of the moral universe bends toward justice, as Martin Luther King Jr. noted. And when it does, that bend in history throws past wrongs into harsh, high relief. Icons topple.

The scrubbing of Erie Catholic Bishop Emeritus Donald W. Trautman’s legacy from Gannon University on Friday occurred in the spirit of the Catholic Diocese of Erie trying to come to terms with a dense, sinful past and take a stand on the right side of history. As reporter Ed Palattella detailed, Gannon’s Board of Trustees on Friday removed Trautman’s name from a building and lecture series and stripped him of an honorary degree.

We have had our differences with Trautman and his prickly resistance to our efforts well more than a decade ago to reveal the truth about local clergy sexual abuse. Even now, he, in contrast to his successor, Bishop Lawrence Persico, does not believe the public has a right to know the names of clergy and laity credibly accused of abuse.

But even we found Gannon’s move to erase Trautman’s legacy jarring. The forceful break with the past testifies to the enormity of the reckoning that’s confronting Roman Catholic institutions across Pennsylvania.

Gannon cited state Attorney General Josh Shapiro’s grand jury investigation of clergy sexual abuse in announcing its decision to remove “all awards and honors bestowed” on Trautman, but did not cite what specific details precipitated the move. Instead, the university’s board said it wanted to affirm its commitment to the well-being of students and the Catholic tradition, which “compels us to give voice to victims and to provide for the protection of children and vulnerable adults.”

Trautman responded indignantly and yes, it was a harsh repudiation. The bishop was never accused of abuse and, as Persico has said, Trautman did more than his predecessors to root out abusive clergy. He led the effort to defrock 16 abusive priests.

The grand jury report, of course, took a different view. Shapiro pointedly singled out Trautman for failing to act aggressively enough in two cases.

No longer is clergy sexual abuse the stuff of isolated arrests or appalling findings about one diocese or another. Shapiro’s investigation of six dioceses, including the Catholic Diocese of Erie, revealed such sweeping and calculated failures of leadership that the question of how to move forward with moral authority begs for an answer.

More than 300 clergy abused more than 1,000 children in part because leaders put the institution above the protection of the most vulnerable. How to make it right?

Gannon’s actions are a start — a declaration of loyalty not to errant church hierarchy but to church as essence — the tradition that cares for the least, above itself.
