Any Navy person can request that. Obviously the criminal jerk wanted his grave-site to be a point of pilgrimage and tearful genuflecting. I'm surprised he hasn't tried to install an 'eternal flame.'
I still think there must be some way to covertly take portions of bladder release into the grave-site and secretly release it . . . until the grass dies and the aroma fits the inhabitant 24/7.
Ahhh welll, perverse fantasies can be lain aside. He's highly likely dealing with much more serious concerns where he is, now.
