I really dislike "stacked" charges. Maybe that's the best way to differentiate between "a burglary", "a burglary where an innocent person was involved", "a burglary where 3 innocent people were involved," and "a burglary where 3 innocent people were involved and made to do stuff beyond 'getting robbed'".
But assuming "equal" charges, is involving three people 3x as bad as involving one? Is "forcing people to move" 2x as bad as just robbing them?
