The author avoiding law enforcement leaves the perpetrator no one to blame but himself. The author shows that he is innocent of the hate that was delivered to him, which leaves only the perpetrator responsible for the crime. If the author had involved law enforcement there is a reasonable chance the perpetrator could not have made the same connection.

I think the authors intent was to show the perpetrator why his actions were unjust, where law enforcement could only punish the actions for being illegal. Of course a judge or jury could lecture him but he already knew it was illegal and inhumane, that knowledge still didn't influence his behavior.
