At least where I live in the UK half the police have guns, they're just locked in their car 99.999% of the time. A lot more UK police have guns than most people think. Any car with a 5 point star (orange in my area) is an armed response vehicle.
Maybe US cops need to just leave their guns in their cars more often?
