evidence: Nevertheless, the widespread public perception that crime is rising — a perception reinforced by presumptive Republican presidential nominee Donald Trump and many other GOP candidates — could figure prominently in November’s election. And state legislative and gubernatorial candidates from both parties likely also will cite crime statistics on the stump. [...] In May, Trump wrongly called FBI data showing a decline in crime "fake numbers." This month, he erroneously claimed that the FBI’s crime statistics exclude 30% of cities, including the "biggest and most violent." [...] The Council on Criminal Justice, a nonpartisan think tank, released a report this month urging police and the federal government to provide more timely crime data. The report emphasizes that crime data, especially national data, often lags up to a year, which hampers public understanding of crime trends and limits officials’ ability to make informed policy decisions to proactively address public safety issues.
