“I want my phone call!”

Do you have the right to make a phone call if you are arrested? Not in Sweden. In fact, not in most countries. So how did people come to believe that the American Miranda rights (“You have the right to remain silent,” etc) apply across the globe?
Hollywood, of course. Isn’t it time Swedish crime film directors set us straight?
Or even better, isn’t it time arrested Swedes were also permitted a phone call? Swedish Moms get worried too, you know.
