As reprehensible as is the crime, it is clear that she is mentally ill—however not so mentally ill as to avoid punishment in any way.
My point is that she is a mental aberrant, who needs to be studied in prison. Not with the hope of curing her, but with the idea of profiling her, for the next time a young girl becomes a ruthless killer. Maybe someday stopping a different killer before they kill.
CAT scan her brain, go over her fluids with a detailed analysis, examine her DNA. If there is an organic reason for her being this way, find it.
She is of no more value than a lab rat, but she does have value *as* a lab rat.
The life of the girl she killed cannot be restored. But preventing such murder in the future is worth the effort. Likely just a few weeks out of the rest of the life of this killer.
I agree with you. The potential value to society of the information should take precedence over concerns such as privacy.
She would probably not object anyway. Being a lab rat is more fun than cleaning toilets or making license plates.
