Earlier quoted context omitted.
Actually, the best way that doesn't get you bogged down in battery charges (for beating a teenager) or manslaughter charges (oops, your barbed wire caused a fatal infection) is social services that help fight poverty and teenage vagrancy (and possibly an accessible iPhone model that takes the edge off of the iPhone jones/envy that your iPhone marketers purposely built).
You might have missed the point. You don’t get battery charges when there isn’t a functioning state with courts, police and prisons. City fortifications are an indication that the functional unit of society has compressed to city scale. It can collapse further to single buildings — castles and further to nomadic warring tribes.
