Correct Answer - Option 1 : Shoot the criminal only on his leg so that you prevent him from escaping
Shoot the criminal only on his leg so that I can prevent him from escaping is the most suitable course of action in such a situation.
This way the criminal won't be able to escape and also the life of the criminal is not under threat.
Hesitate to shoot him because he too is a human being will only allow him to escape which definitely is not a good idea.
Negotiating with the criminal to gain time won't help as the person is a criminal and wants to escape. No way the criminal is going to listen to me.
Waiting till extra-help arrives from a police station at a distance will only help the criminal to escape.
Hence, 'option 1' is the correct answer.
