I don't know exactly how to take this. Never having been jail, I don't know from first hand experience, but don't think I would like it. A few hours compared to days locked up.
How does the family feel about strangers attending the funeral? how did they dress and behave, did they sign the book?. A funeral is part of the personal healing for the family and friends. I respect the ceremony some feel they need, even when I think it is bazaar.
Maybe having to attend the autopsies or clean up the scene would have had more impact.
