So there had been a school beating case in Louisiana.
Now, one teen is guilty of of aggravated second-degree battery and conspiracy charges
Not speaking here about that witnesses provided conflicting testimony ...
The aggravated battery charge against Bell involved the use of a dangerous weapon. Although no evidence of a gun, knife or other weapon was introduced, [DA] Walters argued, and the jury agreed, that the tennis shoes Bell was wearing at the time of the attack qualified as a dangerous weapon.
There are certainly some more questions about this case.
For instance, the court here can reduce/change the DA's charges.
We don't have a jury, but the lay judges are informed by the judge about special legal terms, e.g. what is considered legally as a "dangerous weapon". (Though they certainly can come to a diferent view .... and held that.)
