Cbs news has learned of a troubling increase in Sexual Misconduct cases involving agents with the u. S. Customs and Border Protection agency. That is the largest federal Law Enforcement agency with 45,000 agents. Heres anna werner. Reporter for eight years james tom shack handled Sexual Misconduct investigations as the chief of internal affairs at u. S. Customs and Border Protection, and what he saudis turned him. Between 2012 and 2014, he found there was a spike of more than 35 Sexual Misconduct cases against agents, a rate he says was significantly higher than in other Law Enforcement agencies. What was your reaction to that . A problem that i believed was a significant and serious problem was perhaps even worse than i thought it was. Reporter so last April Tomsheck emailed his boss, the head of the agency, commissioner gil kerlikowske, about the disturbing and disproportionate number of cases in the agencys workforce. What response did you receive . I did not receive a response. Reporter a cbs news investigation found in the last six years at least 21 customs or Border Patrol agents have been indicted or plead guilty to sexual offenses both on and off duty, ranging from Sexual Assault posession of child pornography and child molestation. Five agents were arrested just in the past year. And tomsheck says in some of the cases he found. I believe they were persons who had likely offended before that had gone. Their acts had gone undetected. Reporter youre talking about serial offenders. Potentially. Reporter that sounds shocking. It certainly is a matter of great concern. Reporter tomsheck, a 23year veteran of the secret service, blames the problems in part on a lack of screening for more than 15,000 agents hired between 2006 and 2012 and never given polygraphs. Now standard procedure for new hires at the agency. According to tomsheck, one of those not polygraphed was agent esteban manzanares. Sources say he picked up a woman and two teenage girls trying to cross the u. S. Border along the rio grande, sexually assaulted them and attempted to kill two of them. He later brought one of them back to his apartment and raped her. When federal agents knocked on his door, he committed suicide. Tomsheck believes all agents should take a polygraph every five years which is required in the f. B. I. I believe there are many persons in the Organization Today that if subjected to periodic polygraph screening would be found to be unsuitable. Reporter tomsheck says after bringing this problem to light, he was pressured to resign from customs and Border Protection and retired early. The agencys commissioner declined repeated requests for an interview but an Agency Spokesperson told us in a statement the vast majority of cbp employees do the right thing every day. But that spokesperson also told us that in the past six years the agency has had 285 documented complaints of or allegations related to Sexual Misconduct. Scott .
