A Seattle attorney on Monday released the names of nearly 1,900 men who were expelled from the Boy Scouts of America for alleged sexual abuse between 1970 and 1991.

The spreadsheets compiled and released by Timothy Kosnoff, a plaintiff's attorney who has sued the Boy Scouts on behalf of more than 100 alleged victims, identifies many men who have never been reported to police or faced criminal charges.

In addition, Kosnoff released brief summaries of 3,200 other cases of suspected sexual abuse dating to 1948, without naming the alleged perpetrators.

"It's an opportunity for the public to evaluate the information the Boy Scouts has had and decide for themselves," Kosnoff said.

Kosnoff did not release the underlying Boy Scout files that his spreadsheet was based upon because they had not been redacted of victims' names. His action comes days before some 1,200 redacted files are expected to be released by another set of attorneys in Portland as a result of an order by the Oregon Supreme Court. Those files span 1965 to 1985, significantly overlapping with Kosnoff's.

Together, the releases will give the public the widest window yet into confidential records that the Scouts have used for a century to keep suspected molesters out of the organization. They are known inside Scouting as the "perversion files."

In 2011, Kosnoff gave The Times copies of his nearly 1,900 files spanning 1970 to 1991. The newspaper analyzed them and in August began publishing a series of stories on what they reveal. (MORE)
