They are charged with 1st degree murder ... not a charge I can see a jury, if a good defense attorney does his job searing it, coming down with a guilty verdict on especially with “youths” since only one was over 18 years old. Sorry to be negative but I just don’t see at least one person on a jury not thinking “those poor kids ...” or “they weren’t directly responsible ...” that would hang the jury.
Personally I think there should be a specific change for complacency resulting in death which would be tacked on to the crime committed that resulted in the death and its sentence would not be served concurrently but consecutively.
