In reference to your second point, racially motivated crime is taken very seriously in Ireland.

Traynor was apparently subjected to sustained and horrific racial abuse based on his being Jewish. There has been an escalation of attacks on Jews in Europe by Islamists and neo-Nazi groups. This, combined with death threats and the fact that the abuser knew where Traynor lived would very definitely attract the full attention of the law.

There is either a problem with the police here, or with the story.
