I grew up in San Diego with coyotes in my yard.
I also lived in southern New Mexico for several years (just as arid as southern Arizona) and experienced a record heat wave of 115-120 temperatures for about 2-3 weeks.
Stop exaggerating. The Phoenix heat only peaks in the middle of the day. Most of the year is quite pleasant, and even in the hottest part of the summer, it's still nice outside before 10 and after 5-6. The evenings are beautiful and there's more than enough light to play outside safely. Evening is even the best time for catching the wildlife. Coyotes are primarily nocturnal and are more scared of the kids than the kids are of them. If your kid is old enough to play outside unsupervised, they're sure as hell old enough not be bothered by coyotes.
And believe it or not, even in Phoenix there's a lot of wildlife if you'd just stop to look. Lots of cool insects, birds, lizards. I'm sure there's rabbits and squirrels as well (hint, the coyotes eat something, and it ain't bugs). Sure, you don't have anything as big as a deer, but there's a lot morde wildlife than you realize.
But you probably miss all that because you assume it's hostile out there and instead spend your evenings watching prime-time TV or playing video games.
Oh, and one last thing. Explain the exploding flashlight bombs? Let me guess, something like exploding a mailbox or the like? The people pulling those pranks like to do it when no-one is around to see them. If people are out of doors, actually using their yards and public spaces, then miscreants wouldn't be able to do the shit they do.
