Question: Passage: The law of criminal procedure in the United States consists of a massive overlay of federal constitutional case law interwoven with the federal and state statutes that actually provide the foundation for the creation and operation of law enforcement agencies and prison systems as well as the proceedings in criminal trials. Due to the perennial inability of legislatures in the U.S. to enact statutes that would actually force law enforcement officers to respect the constitutional rights of criminal suspects and convicts, the federal judiciary gradually developed the exclusionary rule as a method to enforce such rights. In turn, the exclusionary rule spawned a family of judge-made remedies for the abuse of law enforcement powers, of which the most famous is the Miranda warning. The writ of habeas corpus is often used by suspects and convicts to challenge their detention, while the Civil Rights Act of 1871 and Bivens actions are used by suspects to recover tort damages for police brutality.

Answer: What have US legislatures been able to enact successfully?


Question: Passage: Gender identity forms an important part of identity in psychology, as it dictates to a significant degree how one views oneself both as a person and in relation to other people, ideas and nature. Other aspects of identity, such as racial, religious, ethnic, occupational… etc. may also be more or less significant – or significant in some situations but not in others (Weinreich & Saunderson 2003 pp26–34). In cognitive psychology, the term "identity" refers to the capacity for self-reflection and the awareness of self.(Leary & Tangney 2003, p. 3)

Answer: What type of identity is less important in psychology?


Question: Passage: The so-called "Sack of Palermo" is one of the major visible faces of the problem. The term is used to indicate the speculative building practices that have filled the city with poor buildings. The reduced importance of agriculture in the Sicilian economy has led to a massive migration to the cities, especially Palermo, which swelled in size, leading to rapid expansion towards the north. The regulatory plans for expansion was largely ignored in the boom. New parts of town appeared almost out of nowhere, but without parks, schools, public buildings, proper roads and the other amenities that characterise a modern city.

Answer:
What is the term for the building boom erected many fine buildings?
