It's interesting that the article states he heard his dogs barking... farm dogs don't just bark in my experience.
I think both parties should have to live with the decisions they made - Maurice should do some community service and redo his PAL training, also get some new dogs with bite. Watson should deal with the fact his arm is going to hurt forever because he's a &^@#ing scumbag and his lingering pain and mental anguish is caused by his own scummy nature.
