The use of dump trucks and garbage trucks to harden the start/finish area of the April 6, 2019 Milwaukee Marathon caught my attention. I have run many races of varying lengths and locations and not previously noticed this type of security measure.
Tip: Use Municipal Vehicles to Increase Security at Temporary Mass Gatherings
There are many threats to mass gatherings — concerts, marathons, parades and rallies — ranging from improvised explosive devices, active shooters and vehicle terror attacks. Since many mass gatherings, like a marathon start/finish area, require temporary closure of city streets and limited access to official vehicles, one of the actions event organizers and local government hosts can take is to use municipal vehicles strategically to block and control street-level access.
