  13. 13. CY ConclusionBERC Capacity of human mind is unfathomable. It is not possible toRI eliminate cyber crime from the cyber space. It is quite possible toME check them. History is the witness that no legislation has succeeded in totally eliminating crime from the globe. The only possible step is to make people aware of their rights and duties (to report crime as a collective duty towards the society) and further making the application of the laws more stringent to check crime. Undoubtedly the Act is a historical step in the cyber world. C Further I all together do not deny that there is a need to bring changes in the Information Technology Act to make it more y effective to combat cyber crime. I would conclude with a word of caution for the pro-legislation school that it should be kept in b mind that the provisions of the cyber law are not made so stringent that it may retard the growth of the industry and prove e to be counter-productive.C r ime CYBER CRIME | 21/05/2011
