The implication being that the police aren't doing a very good job of contacting people about warrants. The first they're hearing about it is by seeing themselves on Pinterest. Imagine the number of increased arrests if the police started using email.
Its rather different, but we are doing a load of outpatient healthcare work for an overworked public health board. Often calling patients multiple times over several days (on cell phone and landline) produces no contact with the person we are after. Posting a letter asking them to call us nearly always works. It's a slow process, but even when you know where someone lives, getting hold if them is hard.
