Kansas City, Kan. ? A police officer caught filming under a teenage girl’s skirt at a St. Patrick’s Day Parade resigned Friday, the Kansas City, Kan., Police Department announced.

Victor D. Waller, 45, pleaded guilty to disorderly conduct Wednesday. He was sentenced to two years’ probation and must attend 12 counseling sessions and pay a $100 fine as part of a deal with prosecutors.

If he does not complete the counseling or breaks probation, Waller will have to serve 90 days in jail, city prosecutor Lowell Gard said.
