An anti-drug policy that reduces the supply of heroin might

1. increase street crime because the addict's demand for heroin is highly inelastic.

2. reduce street Crime because the addict's demand for heroin is highly elastic.

3. reduce street crime because the addict's demand for heroin is highly inelastic. 

4. increase street crime because the addict's demand for heroin is highly elastic.

3. Most of us would like to live in a world were crimes are reported and dealt with, but we’d prefer to have others bear the burden of reporting a crime. Suppose a crime is witnessed by 76 N people, and suppose the cost of picking up the phone and reporting the crime is c > 0. Begin by assuming that everyone places a value x > c on the crime being reported, and if the crime goes unreported, everyone’s payoff is 0. Thus, the payoff to me if you report a crime is x, and the payoff to me if I report a crime is (x - c). (a) Each person then has to simultaneously decide whether or not to pick up the phone to report the crime. Is there a Nash equilibrium in which no one reports the crime? (b) Is there a Nash equilibrium in which more than one person reports the crime? (c) There are many Nash equilibria in this game. What do all of them have in common?

The relationships between a forensic anthropologist and a forensic archaeologist can be likened to that between:

1-​a coroner and a pathologist.

2- ​a forensic crime investigator and a funeral director.

3- a forensic pathologist and a crime scene investigator.

4- ​a police investigator and a crime scene investigator.
