Who is more important?

A few days ago, on the way to train I was listening to the radio. In the news, they said some officer who was being investigated on a murder he might have done years before and was to testify about the case was killed in a driving accident. The way they presented the news seemed that they were not sorry about his death. Then in the same news episode, there was one about an accident that apparently someone had deliberately hit a police horse and they had to put off the horse because of his injuries. The interesting thing was that they seemed really sorry about this incident, specially how it must have been hard for the officer to terminate the poor horse. Anyways, the reaction on this two events was interesting for me.
