Nothing wrong about it. On a deeply personal level, I believe in an Eye for an Eye. It has little to do with the police vs. the civilian. It has to do with the individual.
This disgusting lunkhead beat the cop into unconciousness, and the cop should be given the opportunity to even up the score, but not to kill him (which would be excessive, as the cop still lives).
