GTO, my favorite manga of all time, featured a teacher who got caught doing exactly this except it was more of an outhouse instead of a church:
Pastor Allegedly Videotapes Women, Girls With Hidden Camera
Four Girls On Tapes Were Under Age 10
GREENVILLE, N.C. — A North Carolina pastor is charged with sexual exploitation and peeping after investigators found videos of women and girls at his church undressing and using the bathroom.
The 54-year-old minister, Leon Harris, has been released on bond, but was ordered to stay away from Rose Hill Free Will Baptist Church.
Pitt County detectives said at least eight females were videotaped on June 9, including four girls under the age of 10.
The arrest warrant said the videos are believed to have been recorded by two miniature cameras installed in a church bathroom.
