2. unwise; the additional crime is estimated to cost society $18 billion while the cost savings from decreasing the size of the police force was only $3 billion
3. unwise; the additional crime is estimated to cost society $10 billion while the cost savings from decreasing the size of the police force was only $3 billion
4. wise; the additional crime is estimated to cost society $3 billion while the cost savings from decreasing the size of the police force was $18 billion
