Lawyer: In addition to any other penalties, convicted criminals must now pay a "victim surcharge" of $30. The surcharge is used to fund services for victims of violent crimes, but this penalty is unfair to nonviolent criminals since the surcharge applies to all crimes, even nonviolent ones like petty theft. Which one of the following principles, if valid, would most help to justify the reasoning in the lawyer's argument? ['Convicted thieves should be fined an amount at least as great as the value of the property stolen.', 'A criminal should not be required to pay for services provided to victims of crimes that are more serious than the type of crime the criminal has been convicted of.', 'The penalties for a crime should be severe enough to deter most people who would commit the crime if there were no penalties.', 'A surcharge intended to provide services to victims is justified only if all proceeds of the surcharge are used to provide services.']
