星期天，華盛頓特區放煙火，一系列的聲響引發華盛頓特區 Amtrak 內的民眾一陣恐慌。
之後當地公共安全和司法部副市長 Kevin Donahue 趕緊在東岸時間下午5點發放聲明：「這幾聲巨響是煙火被點燃的聲音，並沒有槍手或是其他槍擊事件。」
WRC-TV報導，醫務人員在現場對驚恐發作的3民眾進行治療。 在今日美國的一份聲明中，Amtrak 警方表示沒有受傷事件。
以下是民眾在推特上貼出當時放煙火時，聽到聲音的恐懼：
Just had to barricade myself in the bathroom at Union Station because there was a report of a gunman and loud shots. Everyone was panicking. Turned out thankfully to be firecrackers, but eugh. What a terrible fright. ?

We were in union station in dc when fireworks were mistaken for gunshots today. Saw a crowd of people running. Didn’t ask questions, just ran. It was truly terrifying. I hate that this is the world we live in today. Just want to send love and gratitude that everyone is okay.
