A man comes up to you and confesses that in the rage of his anger he has stabbed his wife with a knife. What will you do next?
1
Arrest him for murder although he has made a confession because a crime is a crime and then investigate the crime scene
2
Arrest him and tell him that you will try and reduce his sentence since he has made a confession upfront
3
Let him go as he has done a good deed by confessing his crime
4
Ignore him as he can be a mad person
