在劫持人质案件正在发生时或发生后较短的时间内,一般会有少数警察在案发现场或早于其他参战警力,先期到达现场。从少数警察临案,到参战各警种分队陆续到达案发现场展开行动之前这一阶段,为劫持人质案件的前期处置阶段,属劫持人质案件处置行动准备阶段的范畴。 During the time when hostage-taking cases were taking place or shortly after the incident occurred, a small number of police officers generally arrived at the scene prematurely at the scene of the incident or earlier than the other war-deterrent police forces.
