I think it is fine and good that he is dead. I have been in favor of the death penalty for vandals for a long time. (Mindless destruction of personal or government property.)
It has probably been as long since his crime as the average murderer spends on death row.
He didn't destroy anything, he simply changed the sign in a non-destructive way.
To change the sign, he used stones and rope and erected the fabric as though he was hoisting sails.
Anyways, to most sane people, using the death penalty against "vandals" is an overreaction.
