Possibly your right. I thought sometimes a person tries to murder a second person. However, he may wound the victim without killing him. Then he is charged with attempted murder.
The reason I asked the question is that I had read that the murder rate has declined. Then I read a claim by one man that actually emergency room doctors are saving more victims and that the reason for the decline in the murder rate is that the victim doesn't die and so the crime is reported as an attempted murder.
