My righteousness rating is slipping.

Not sure why righteousness is hard to understand:

Rating (ways it) Drops:
Randomly

Rating (ways to) Increase:
Tap Side-show Bob (if unowned, or visiting Other Springfield)
Remove Graffiti

Permanent (meaning you will never see your rating drop, at least to a low value - number required increases over time):
Place Training walls
(If owned) Nero's Wall (from Casino event)

I've never seen (valid) data that cites why this rating drops. Only theories. I conclude it does it on its own.

Summerized perfectly here. It should be added that under the PERMANENT category, some items/buildings also increase rightousness: swat van, police building, springfield prison, minimum security prison
