The problem is not just with people who want to walk places, but people who want to mug/murder/rape those that do.
This is a completely irrational (though commonplace) fear. Criminals aren’t hiding out in bushes in desolate parks to mug or rape random people. Muggings most commonly happen in side paths off of busy high streets because criminals, being people, like to hang out in stimulating places where they won’t get bored. They’re not going to be donning ghillie suits and lying patiently in wait for however long in uncomfortable brush for a hapless victim to cross their path. The muggings are crimes of opportunity. Rapists are most commonly somewhat trusted friends or acquaintances who have access to people when they’re in vulnerable states in private, protected spots.
Thinking parks and parking lots need to be lit up like Christmas to deter crime is just a veneer of rationalization to cope with the standard childhood fear of the dark. It is not backed by data or evidence. The actual main public safety concerns when it’s dark out are trip-and-fall hazards or collisions with or vehicles who can’t react fast enough when things pop out at them, not muggers and rapists. Having the nighttime environment overly lit actually makes shadows starker and blows out people’s night-vision so they can’t find things. If anything, it makes the edge case where Sam Fischer is hiding in the bushes more dangerous rather than less.
