Good, now they have found his body in the vault, brick it up and leave him in peace.
In an ideal World a law would be passed were NO guns were allowed and all those out there destroyed, trouble is the law makers are not going to take a risk of trying to pass that without making sure they are armed first.
Well I think, that they should see what are his books about, maybe he has something we don't know now, some "secret books" or some long lost ones. Ofcourse if they are still readable. Then after reading/scanning all of them, put that back and bury him as he wanted to be buried.
