From the Wisconsin statute (BBM): I'd say that: (1) is arguably the case given their ages (if they were 16 or 17 that may be different) (2) I have no idea how this could ever be proven true! The reason they're being tried as adults is the nature of the crime. So its always going to be life versus out at max age 25. And the goals of the juvenile and adult system are not the same - its more rehabilitation for the former versus punitive in the latter. (3) Cases in juvenile court are not open - so how could any such trial act as a public deterrent for any crime? The above requirements appear to be written to make it highly unlikely that any reverse waiver appeal will succeed. Doesn't look like this case will wind up in juvenile court.
