It matters because it is a psychological stress.Punish people who are shameless and are real criminals. 1st time cautions always happen due to lack of knowledge.
A small mistake during university time is punishing me for a life time. The amount of stress it has caused is really unexplainable . It would be a great help by government if they remove 1 time cautions atleast after 10years time , not to get any benefit but it really removes all the stress and gives peace of mind.
