Is BLM's dead fiance buried under the lawn?
If you asked them to “please do not do that”
I would not ask them. I would let them grieve in their own way. If I didn't like their display, I would ask the cemetery caretakers to just remove the display in the normal manner they remove stuff people leave on graves. I would not make a big stink about it.
Of course i'm not some pretentious reverend "Doctor", so I don't have the "high and mighty" syndrome.
The article further down says Hagan kept doing up to 10 times even after the Dad asked him multiple times to stop. Then the complaint was made. It changes the storys complexion.
