JT Jane, Chardon High School Shooter, Sentenced

JT Lane, the shooter from the February 27 Chardon High School Shooting, was sentenced to life in prison.

Lane is not eligible for the death penalty  since he was 17 at the time of the shootings.  There were five shooting victims in all, and three of them tragically died.

During his sentencing today, Lane hardly seemed remorseful   He wore a shirt with the word "killer" handwritten on it with a black marker and smirked through the entire preceding.  Once he was sentenced, he gave the finger to the court as well as some disgusting choice words.

Is the sentence too harsh?  What should be his punishment?
