PROBLEM TO BE SOLVED: To protect a person against vicious perpetrators, or vicious ownerless dogs, monkeys, bears, and the like, since recently, abrupt increase is observed in crimes, including stalking, bag snatching, robbery at convenience store, and the like. SOLUTION: A pistol-type spray for crime prevention generates a high threat-warning sound the first time and discharges repulsing tear gas the second time, when trigger is pulled. Consequently, a threat action can be distinguished from a repulse action. The tear gas for repulse at the second time is irradiated, without missing the target with proper timing, while the culprit, a bear, or the like will wince at a high warning sound.
