“迅速调查”
用英语怎么说？

Witnesses offered contrasting accounts of the encounter. An onlooker reported that an agent stepped directly in front of the vehicle and fired at point blank range. In response, federal authorities insisted the officer acted strictly in self-defense against an act of domestic terrorism. Meanwhile, the state governor urged the public to push back against federal propaganda and promised an expeditious investigation to ensure complete accountability. The fatal encounter occurred merely a mile from where George Floyd was killed, prompting hundreds of outraged residents to gather for a vigil and demand justice.

目击者对这起冲突给出了截然相反的描述。一名旁观者称，一名特工直接走到车辆正前方，在近距离开枪。对此，联邦当局坚持认为，该官员纯粹是针对一起国内恐怖主义行为进行自卫。与此同时，该州州长呼吁公众抵制联邦的政治宣传，并承诺展开迅速调查以确保彻底问责。这起致命冲突发生在距离乔治·弗洛伊德遇害处仅一英里的地方，促使数百名愤怒的居民聚集守夜并要求讨回公道。
