Should a teen go to prison for causing a "Texting-While-Driving" Death?

"A Massachusetts teenager was sentenced
this week to two years in prison and loss of his license for 15 years
after being convicted of motor vehicle homicide. Aaron Deveau, 18, is
the first driver in the state to face such charges. On February 20,
2011, Deveau was driving and his vehicle swerved across the center line,
crashing head on into Daniel Bowley's truck, causing life-ending
injuries."

"Bowley, a 55-year-old father of three, sustained massive head trauma
from the accident and spent 18 days in a Boston hospital before passing
away. Deveau pleaded not guilty to texting while driving, and claimed in
his testimony that he was distracted by the amount of homework he had
and had sent his last text message in the parking lot of the grocery
store where he worked. He said he had left the phone on the passenger's
seat the whole time, but phone records showed that Deveau sent a text
message at 2:34 p.m. and received a response at 2:35 p.m.—the time of
the crash."
