Rapidly deployable countermeasures at protected perimeters and structures

Law Enforcement Officers (LEO) are often called upon to secure buildings and structures during events with a large number of attendees. During celebratory or protesting events, portions of crowds may become destructive or aggressive and enter or attempt to enter restricted, private or protected sites or structures. Law Enforcement Officers (LEO) deploy physical barriers and other countermeasures in an attempt to mitigate incursions. However, protection of sites against incursions would benefit from an additional layer of advanced technology solutions to delay crowd advancement, prior to the need for direct engagement, while LEOs can muster additional staffing and/or resources. There is a need to develop a capability to immobilize aggressors through deploying a substance/material to a surface which would, remain passive until activated or be activated concurrent with deployment. The capability will need to be able to be rapidly deployed in an active state or deployed beforehand and rapidly activated to prevent malicious actors from breaching perimeters. If the identified solution exists in ready-to-deploy state, it must blend in aesthetically to existing infrastructure prior to activation. Successful deployment of this technology would deter or delay incursion to allow LEOs the time and space needed to dispatch additional reaction forces and countermeasures to defend sites or structures. The desired technical solutions would minimally occupy the initial staff once activated and should not contribute to LEO entanglement with the crowd. Lastly, once activated, the solution should be highly visible (brightly colored, impregnated with flash material, etc.) so as to mark the deployed location and prevent any person not attempting incursion from accidentally becoming immobilized. Key requirements of a proposed solution must include: Preparation/set-up time to apply solution should not exceed 4 hours per acre Ability to be activated near instantaneously (threshold: < than 3 minutes to activate and objective: =/< than 3 seconds to realize initial effectiveness) Once activated, remain effective until no longer needed and/or be able to be quickly reactivated within original activation threshold Once activated the solution should be highly visible both at night and during the day (containing a bright color, flash material, etc.) Ability to be cleaned up safely with minimal logistics within 12 hours and not require advanced or specialized personal protective equipment (PPE), beyond Level D and N95 mask, to handle deployed material Solution must be effective in all four seasons Low-cost, targeted coverage cost of $15,000 or less per acre Solution be compliant with guidance found in DHS Policy Statement 044-5, Department Policy on the Use of Force and must operate within legal authorities established under Title 18 U.S. Code 3056 Technical solution should NOT include: Launching of projectiles Energy-based systems or weapons Physical barriers Requirement for active steering or guidance by LEOs to be effective Factors that could be considered beneficial when key requirements are met: Mobility of solutions that could facilitate protection of locations based on evolving or emerging event concerns Technology solutions that are reusable subsequent to deployment and activation Resilient to weather and other environmental and situational conditions Minimal potential for serious injury when deployed and activated Compact storage Lightweight and man-portable (time required to be worn or lifted should be balanced with weight and size)
