Yes! It is true that people have more fun mud slinging at Bihar. It has more or less become a joke. However, keeping public over reaction towards such incidents in Bihar, fact is fact. Bihar is in much horrible situation than many other states. What even more saddening is that while most other states are moving forward, Bihar has been moving backward. Also, there is difference between some of the incidents you reported in other states to the current story in Bihar. While in these incidents the evil doers where doing in private harboring the fear, of varying levels, that the society might punish them this incident in Bihar shows how immoral activities have come to be accepted as the general state of affairs.
