Is This Right?

I read in the newspaper (The Daily Nation) that a Matatu driver killed 3 people in Nairobi the other day. He was trying to pass some cars on the curb and hit a woman with a child and a young man. He went to court and they sentenced him to five years of prison for each person. That means he will go to prison for 15 years, but, he is allowed to serve the three sentences at the same time. This only leaves him with five years of prison time. However, in Kenya, a day and a night are counted as two days. This cuts down his time spent in prison to only two and a half years for killing three people. The Matatu drivers are the most dangerous drivers on these roads and many people are killed every year in crashes or by being hit but there is never any true justice. I understand that the Matatu driver didn't intentionally kill the three people but manslaughter of three individuals in the states would be 25 years or more, never two and a half. I can't imagine what the families are thinking.
