Backyard astronomers need to fuck off to a remote valley somewhere. Putting lights in outdoor areas is super useful. It reduces crime; makes people more likely to walk or bike instead of driving; fewer car accidents, etc.

Incorrect. Light does not reduce crime.

Why is crime directly proportional to skin darkness then, huh?

LEDs are already directional.

LED light reflects off of what it hits, that's how you an see by it.

Interestingly, it does not all bounce directly into eyes, some of it just wanders off in odd directions.

This. The little bastards are so fucking energy efficient, they make lights much brighter than traditional street lights.
