Let me make a few comments before directly answering your question.
In this day and age, what passes for pranks are no longer harmless. By harmless, I mean in the past the bulk of pranks didnt cause irreversible physical harm to people or property. By harm, I mean the prank didnt inflict real or potential medical trauma on a person. Or permanent physical damage to property. Were there exceptions back in the day? Im certain there were, but as I said, the bulk of pranks were basically harmless.
Today, there is a dedicated mission among pranksters to be either or both gross and destructive.
Were seeing kids pushing elderly wheelchair bound people down escalators. {Youtube removed the video due to law about I.D.ing juveniles in court cases}. Food handlers
standing in your food.
Slobbering on your bread. Slashing your tires. Pissing in the offices coffee. Starting
fires on public land (or anywhere).
My point is, what passes for pranks today, have repercussions that are a danger to the life and limb of others. I personally, think that three things are at play. One, is
Dr. Benjamin Spock's grossly misguided influential, books on children rearing. Two, the bullying behavior by so-called social workers toward parents. Now, I admit some parents, maybe too many were/are abusive as opposed to merely disciplining. So some kids do need protection. But social workers have far too much leeway. Three, modern media of TV, movies, and video games encourage gross and destructive behavior. Kids are bombed daily with such media that literally celebrate such conduct.
Now, to answer your question. I believe if someone is dumb enough to damage the rock or Torch Bearer at the UT, they are beyond dumb. I honestly believe we have people who if they found out who did it, are not adverse to grabbing a shotgun and blowing the idiot to Hell because he sure wouldnt be Heaven bound. Theres a reason Lane Kiffin sneaked out of Knoxville the way he did. I can't say I'd have much sympathy for the vandal in this case.
