Been here since 2009.
Yeah man, the cops really aren't exceptionally bad out here. I see cruisers/SUVs out on patrol from time to time, but not at any higher volume than I was used to in Columbus, OH where I used to live.
And as it sounds like you're finding out, the heat ends up not being as bad as you think it is, since the city is built around being able to avoid heat exposure in the summer. Only folks I know getting pelted by the heat long term are folks using public transit, unfortunately homeless people, foolish hikers, or people who work outdoors for a living.
