Blackstone's Police Investigators' Q&A 2017 is the essential revision tool for all candidates sitting the National Investigators' Examination (NIE) examinations. Written in partnership with the best-selling Blackstone's Investigators' Manual, the only study guide endorsed by the College of Policing, the Q&A consists of over 200 multiple-choice questions arranged in the same order as the chapters in Manual, providing the most authoritative means of self-testing outside of the NIE. With four parts, Evidence; Property Offences; Assaults, Drugs, Firearms & Gun Crime; and Sexual Offences, reflecting the Manual, Blackstone's Police Investigators' Q&A presents you with the only format of questions you will see in an NIE examination: Type A. Each question has a detailed and comprehensive answer that highlights not only the correct response, but also the reasoning behind the incorrect responses, allowing you to highlight any gaps or weaknesses in your knowledge. Full cross-references to the relevant Manual paragraphs and Keynotes encourage more effective studying, while a question checklist helps you track your progress. The introductory chapters also contain a useful section on how to study for the NIE, including advice on how to approach multiple-choice questions, practical exam techniques, and a 14-week revision plan. Fully updated for the 2017 syllabus, including coverage of relevant new legislation, the Modern Slavery Act 2015, the Anti-social Behaviour, Crime and Policing Act 2014, the Criminal Justice Act 2015, the Criminal Justice and Courts Act 2015, and the Criminal Procedure Rules 2015, as well as revised PACE Code E (February 2016). There is also revised material covering State of Mind and Criminal Conduct, and a revised chapter on Theft and Related Offences. This product is not endorsed by the College of Policing.
