POLK COUNTY, Fla. --
Polk County officials arrested dozens in a child pornography investigation, including an Isleworth Country Club security guard.

Cutting edge software is making it easier for law enforcement across the state of Florida to target those suspected of downloading and trading child porn, according to Polk County detectives.

A high-profile bust led Polk County authorities to the Isleworth Country Club where they arrested security guard Stephen Kaczmarski and charged him with 28 counts of child porn possession.

The Polk County Sheriff's Office deputies call their latest investigation "Operation Child Shield Two" and said the program has brought in 50 arrests.

Sheriff Grady Judd said during the course of the operation, they were able to rescue eight children who were being actively abused or exploited by adults.

One common complaint from law enforcement is that once they make these child porn arrests, judges are not passing stiff enough sentences.

These latest arrests by Polk County investigators brings the number of people arrested on child porn charges to 141 since 2007.
