Three 19 yr old frat boys being stupid. Stop the presses.
The kids are in deep doo-doo now, though, because there apparently isn't any law against propping items against a statue if the statue isn't actually damaged. So the FBI has been called in to see if it can be charged as a hate crime.
Sorry, the worst these kids should have had was instant expulsion from the university. Was it a racist joke? Oh hell yes. Should they spend five years in the slammer for it? Of course not. This is one of those face-palm moments, when officials have perpetrators, but can't find any law they have broken, so they call in the feds to fabricate one.
