How is Sweden's political environment drive the plot in the novel, Faceless Killers?

Political change plays an important part in driving the plot. Refugees are coming to Sweden because of its open-border policy, and they are kept in ill-prepared and ill-administered refugee camps. Anti-foreign sentiment is on the rise, and concern about Sweden's border policies is mixed up with racist dogma. Wallander finds himself in the middle of a political hot-button topic, called racist by the Immigration Service and accused of conspiring to protect criminal refugees by the nationalist movements.
