I regularly shop at a small local market. There is a 60ish year old man who comes in wearing a mini skirt on Sundays. He intentionally stands near children and makes everybody uncomfortable.

Last month, I came up to him and quietly said something to him. I told him I was an FBI agent and I've been monitoring his activities. He turned white as a sheet and began to tremble. He quickly left the store.

He has not been back since.
