The maximum imprisonment for violating the provisions of the 1964 Act was 06 months whereas the 2010 Bill/Act prescribes imprisonment extending up to 07 years. It is this that has made people question the intentions of the State BJP (right wing) government as in the Indian Penal Code (IPC), imprisonment for such long terms is usually meant for crimes of a far more heinous nature.
The latest Karnataka Prevention of Slaughter and Preservation of Cattle Bill / Act 2010 virtually equates the killing of a cow with the murder of a human. (It's only the economically weaker sections of the society who consume/eat beef in India.)
An offender may be imprisoned from 01-07 years and fined between Rs. 25,000-50,000 or Rs.1 lakh. Draws the lines - us and them, the beef-eaters and those who don't, the killers (bad ones) and the pious/good ones. Reinforces those lines with the draconian, absolute and brutal police power of the State behind one particular section. Removes any distinction between "cow" and "cattle".
