The Guardian article was about a bombing of the relative of a gang leader, which also killed a woman living nearby. The implication was that public name->address lookup played an important role in that bombing, so should be curtailed in order to prevent similar future events.
My complaint is the article presented no evidence supporting that implication.
This linked-to page uses the Guardian article to support their position, but I don't think the Guardian article has any substance.
FWIW, Sweden is one of the countries which requires you to register your address with the government. The Swedish police already have the name->address information and don't need a data broker for it.
