A shooting case occurred in a city. After investigation, the police arrested Li and identified him as the murderer. The reasoning process of the police is as follows: the deceased was shot while passing through the building of city bank, and according to the people on the scene at that time, the bullet was shot from the third floor of the building. That is to say, only those who stayed on the third floor of the building when the deceased was shot can commit the crime. It was proved that Li was on the third floor of the building, so Li was the murderer.
The statement 'Only when the yard is wet can it rain. The yard was wet, so it rained' is similar to the wrong reasoning of the police.
