国家应对措施
美国国土安全部与美国司法部的全国可疑活动报告（SAR）计划（NSI）联合发起了这项行动，旨在培训州和地方执法部门识别恐怖主义及相关犯罪的行为和迹象。NSI 规范了这些观察结果的记录和分析方式，确保将报告共享给由联邦调查局牵头的联合反恐工作组进行调查，并与各州情报融合中心共享进行分析。只有那些记录了合理表明恐怖活动行为的报告才会与联邦、州、地方、部落和领地（SLTT）合作伙伴共享。
In 2010, the Department of Homeland Security (DHS) licensed the use of the New York Metropolitan Transportation Authority’s “If You See Something, Say Something®” campaign for national anti-terrorism and terrorism-related crimes effort. It has promoted the campaign and the message that informed, alert communities play a critical role in keeping our nation safe via partnerships with states, sports leagues, universities, property groups, malls, and transit authorities throughout the country.
Campaign partners are critical in increasing the awareness of the campaign's message by distributing campaign materials and spreading the word about suspicious activity reporting. DHS supports campaign partners by providing print, digital, and video materials to use—including social media content, posters, brochures, web graphics, digital signage, and public service announcement (PSA) videos.
The campaign continues to remain at the national forefront due to recent active shooter events, the Boston Marathon bombing, to name a few. These occurrences can serve as reminders about the importance of the “If You See Something, Say Something®” message.
