I don't know if anyone has read the judges sentencing remarks:

http://www.judiciary.gov.uk/wp-content/uploads/2014/11/r-v-cornick.pdf

The judge said:

  we heard one pupil describe her as
“really caring...she sort of couldn’t do enough for people,
she was just really lovely to everybody.”

Another pupil
described her as “more of a friend than a teacher”. And
another, when asked what she was like, said “she were
wonderful. She were just...she
was so nice to everyone, she
were kind, she’d always stay back late...her main goal for
everyone in that class, she just
wanted them to come on top
and achieve what she knew they could achieve and you
could tell she loved it. You could tell that she loved doing
what she were doing every day.” 

These words from the mouths of children who have just seen one of their best friends murdered in front of them

Thats why we have the justice system to sum up in a balanced and considered way,and thats what stands between us and a lynch mob
