When your kids are trick or treating, you don't want them coming in contact with sex offenders.
That's what Operation Blackout is trying to prevent...
"They're in a lot of everyday neighborhoods many people in Tennessee do not know they have a sex offender living as close as they do," said Probation Manager Elizabeth Hammond.
It took Eight teams of probation officers, Chattanooga police officers, and Hamilton County sheriff deputies to check in on 174 sex offenders in Hamilton and surrounding counties.
Officers had to go door to door and check inside the sex offenders home for any violations.
One of the most common thing we ran into was offenders opening the door without asking who was there.
