They are misdeamenors. No different than getting an underage drinking ticket, in actuality. Misdemeanor battery is just "getting into a fight" and criminal recklessness is the same as "toilet papering" someones house and getting caught. There is no reason to change the venue...pointless and polictical move by the defendant's lawyers to postpone it even further.
None of these kids will get jail...at all. They will get 500 hours of community service and move on. No judge in Hamilton, Hendricks or any other county is going to give these kids jail time, they all have "clean" records. The charges that the prosecutor brought are ones that she is guaranteed to get a guilty verdict on, because the burden of proof is so little. There will be no reasonable doubt that they are guilty of these misdemeanors. It is a sad situation.
But when this goes to civil court (if it does) you will see some pretty serious "shit" no pun intended, come out. But I don't think this will end up there either. It will get settled.
