BOSTON (AP) - Human trafficking convictions at the state level are notoriously elusive, despite crackdown laws that are on the books in all 50 states.
Officials and experts say there's a need for more resources to support trafficking victims, educate the public and train law enforcement.
In about a dozen states, attorneys general are not even authorized to pursue human trafficking charges.
Records requested from all 50 states by The Associated Press indicate a low conviction rate for human trafficking crimes since 2003.
A previous study suggested a 45% conviction rate through roughly the first decade of the laws.
Data shows the conviction rate for federal prosecutions is much higher, at about 80%.
Observers say the Florida massage parlor sting that snared New England Patriots owner Robert Kraft highlights the difficulties with such cases.
