So does this mean that we aren't able to breathe unless we don't go and catch the criminals?

Where do we put these criminals? Is there a seperate jail for them or do we lend the Banhammer?

Also when humans breathe out there comes oxygen besides CO2 as well. Why on earth would we use mouth-to-mouth method if it was only carbon dioxyde? Well if it is a hottie but if it isn't?
