A wide-ranging child exploitation investigation in the Los Angeles area lands nearly 300 people behind bars.  

"Operation Broken Heart" involved 62 federal and regional law enforcement organizations across five counties.  

Some of those arrested include a retired Los Angeles County sheriff's deputy allegedly involved in child pornography, a special needs teacher's assistant who police say sought sex with two children, and a 64-year-old computer programmer who is accused of arranging to meet a 15-year-old at a public park for sex.  

Throughout the operation, detectives often pretended to be minors to lure predators into sting meetings, and investigators are reminding parents to have frank conversations with their kids to keep them safe in cyberspace.
