If someone comes along and deletes one of your issues for whatever reason, you will have no idea who did it or why or when. You will have no idea the issue ever existed. When an issue is deleted, there is no log or history or information about what happened. There is no way to restore it (unless you have a backup somewhere).
We need to be able to have a log history at least. Additionally, there should be a way for an admin to access the entire ticket data -- no matter what. They should be able prevent deletion entirely and lock that down system-wide. It's an extremely frustrating experience that seems to have affected most users.
