Was this fair justice?

Two years ago I was driving an icy road in North Dakota, looking thru my rear view I could see the woman busy texting on her phone, I stopped at a red light and she rear ended me. When the cop arrived, he asked to see the lady's phone, he laid it on the pavement and crushed it with his boot. Crushed to smithereens.

In court, the judge just laughed and not only sided with cop but gave her a very hefty fine. (I of course LOVED it) Do you think this fair or overkill?
