Dimebag was shot by a crazed fan.
I think that deifying anyone, especially in the fashion as has happened posthumously to Dimebag, is somewhat distasteful.
Just because he's dead doesn't make him a no-go area for artistic criticism.
Getting back to the thread I have no tattoos but were I to get any I would be tempted to get an H.R. Giger style tattoo on my spine, where it won't be seen unless I decide to show it off (I don't understand the whole sleeves thing although my uncle has a fair few tattoos about his person).
