Attorney general to conduct study (a) Study (1) In general The Attorney General shall conduct a nationwide study of the prevalence and effect of any law, rule, or procedure that allows a law enforcement officer to delay the response to questions posed by a local internal affairs officer, or review board on the investigative integrity and prosecution of law enforcement misconduct, including preinterview warnings and termination policies. (2) Initial analysis The Attorney General shall perform an initial analysis of existing State statutes to determine whether, at a threshold level, the effect of this type of rule or procedure raises material investigatory issues that could impair or hinder a prompt and thorough investigation of possible misconduct, including criminal conduct, that would justify a wider inquiry. (3) Data collection After completion of the initial analysis under paragraph (2), and considering material investigatory issues, the Attorney General shall gather additional data nationwide on similar rules from a representative and statistically significant sample of jurisdictions, to determine whether such rules and procedures raise such material investigatory issues. (b) Reporting (1) Initial analysis Not later than 120 days after the date of the enactment of this title, the Attorney General shall submit to Congress a report containing the results of its initial analysis, make such report available to the public, and identify the jurisdictions for which the study is to be conducted. (2) Data collected Not later than 2 years after the date of the enactment of this title, the Attorney General shall submit to Congress a report containing the results of the data collected under this title and cause a copy of such report to be published in the Federal Register. 1028.
