> The FBI recorded 61 "active shooter" incidents last year, the highest tally in more than two decades, the agency announced Monday. > The 2021 total, which included incidents occurring in more than 30 states, was 52% higher than the previous year's total and close to a 100% increase from each of the three previous years. > Last year ranked as the seventh-deadliest in terms of active shooting incidents since 2000, the first year for which FBI data is available. > The bureau defines an active shooter as someone engaged in killing or attempting to kill people in a public area in an apparently random fashion. Numbers, therefore, do not include gang- or drug-related shootings, or even all mass shootings. About half of such incidents last year occurred at commercial businesses.
