Visible presence. Some people find it reassuring, a reminder they live in a safe society. Other people find it unnerving, usually because they're up to no good. But also because you want cops to be able to respond to any area of the city quickly.

What do you mean "primed?"
I mean already out and about, rather than enjoying a nice cup of tea in the station. Putting your coat on, going to the car, how long does that take? A minute? Two minutes? That's response time wasted.

Everyone knows the police exist.
Yes, fine, but it's a reminder to anyone thinking about crime that there are people out there who have the authority to take action. I can tell you from past experience living in a shithole town that Friday and Saturday night when pubs are closing, I'm happy to see police about because it means any dickheads looking for a fight or someone to mug will reconsider their plans.
