A string of recent events, including the November 2021 vehicular attack in Waukesha, Wisconsin, have made the need to address attacks on public spaces and venues open to the public and implement the right protective measures increasingly clear and urgent. This session will examine and standards specific to physical security, as well as guidance to cities and venue managers on mitigation measures. International perspectives and insight will be shared from the U.K campaign for Protect Duty legislation (known as Martyn’s Law) following the 2017 terrorist attack at Manchester Arena.
