What is it about the night in Central America

Not really got much to say on his, apart fr why is it everywhere after 9-10 pm is locked up and shut. Everyone nails down the hatches and hides from the night till morning. I don't really get it. Do criminals, thieves, drug addicts and murderes work on a time schedule? Like you can imagine their iPhone alarms ( taut they robbed) going off at 10pm, they wake up from whatever drug induced state they were in and shout to their rather skinny heroin addict wife, "right off to work love got some murdering and stealing to do"
