Harry knows there are some upsides to being stuck in a time warp. On the next day, no one other than Harry can remember what happened the day before. At some point, when he's feeling particularly overconfident, he breaks into Dr. Wohlfahrt's home. Before he knows it, he's under arrest. At the police station, he's informed about his rights, which are constitutionally guaranteed under Germany's Basic Law. It begins with the words, "Human dignity is inviolable," and the state must respect and protect it.

Particularly relevant to Harry's immediate situation, however, is Article 3, Paragraph 1. It states that "All people are equal before the law." One consequence, for example, is that the police may not stop and search people – unless there are specific grounds – and certainly not solely based on their looks – like their skin color. Racial profiling is not permitted. Otherwise, Article 104 is particularly important: Persons in custody may not be subjected to mental or physical mistreatment. Torture is prohibited and punishable by law in Germany. Suspects also do not have to make a statement to authorities and are entitled to a lawyer. The police cannot detain them for longer than 48 hours without a court order.
