Prior to the "theft" were there any indications that this cornerstone was going to be saved or salvaged?
If they were bulldozing this church and throwing it all into dumpsters I don't see the harm in what the guy did. [[Not much different than someone dumpster diving or picking up a discarded piece of furniture at the curb.) On the other hand, if the stone was purposely left in place to be saved then that's a different issue.
