I suppose people aren’t robbed “in broad daylight”, when there are many people on the streets, because standers-by can help the victim, call the police, or take videos that show the robber’s face.
As for rioting, the rioters would rather attack and rob a store when the store-owner isn’t there to defend it or, again, call for help or take photos.
But even if that wasn’t so, there might be game theoretic reasons to rob and riot at night. Suppose police (or other authorities) need to invest some amount of effort to make each hour of the day or night crime-free. They don’t have enough budget to make all hours crime-free; besides, the last few hours require the most effort, because it’s easier to make robbers to delay their robbery by a few hours, than to make them never rob at all.
So which hours should the police invest their effort in? Since robbing affects pedestrians, and rioting affects stores and shoppers, then clearly police should prioritize daylight or working hours, when there are many more people at risk, when people can’t just decide to stay home because they’re afraid of being robbed, and when the police themselves want to have their shifts. And once police are more active during certain hours, criminals will become less active during those hours.
