It's a huge mix of drug-related stuff:
- intoxicated people hurting themselves in others in wrecks, walking out into traffic, fighting others etc
- robberies/shootings/assaults related to drug dealers and rival gangs vs each other
- robberies/shootings/assaults of drug addicts trying to rob the dealers or vice versa
-95% of prostitution and the crimes associated with that which are done to feed drug habits
-80-90% of all thefts/burglaries/home invasions/stolen vehicles/etc all done to feed drug habits
-Sex trafficking, murders while intoxicated, rapes while intoxicated.
Literally the only other reasons crime happen besides drugs are:
- greed over money that has nothing to do with drugs
- issues with relationships (jealous over cheating, etc)
- those who commit crimes for true psychological issues (i.e. serial killers)
