Prevent corruption
Lots of types of crimes can be mentioned but one of them I think is really grave. The rich people of our country do not pay taxes (instead they like to bribe the politicians). How can a country run without taxes? These people are really heartless.
To control these economically motivated crimes and all other types we need an Independent Anti-Corruption Bureau. In our country's perspective, no party government can ever do justice when it comes to anti-corruption measures (Think, on an average, how many criminal cases are there against an MP, minister, party bosses and their cadres).
The two major political parties have always promised to set up the institution but they really don't want such a institution. In fact, some of the parties' big bosses may have to leave the country once IACB comes into being. But, let us not forget, without justice we would have no peace or prosperity in the long run.
