I worked in Galveston Co Texas. I often carried an AR, carried for a couple of years an HK 91 and for a short bit a Garand. I always had a 12ga.
In San Antonio I was stunned at how under armed the Police were, within the 5 sections the city was divided into, one Officer per shift 'could' carry a shotgun and one Officer a shift 'could' carry an AR. They had SWAT but the response time was no better than anywhere else.
