Since capitalism is predicated on the earning of profits and the accumulation of property there is always the problem for the capitalists of securing this profit making and accumulation against the opposition to it from the vast majority of citizens who are exploited in the process. Therefore, the security apparatus of liberal democratic states have always been deployed against the majority of citizens so as to safeguard the capitalist interests. Also capitalism has always been simultaneously imperialist in nature and so it has exploited not only locally in one country but across the globe further increasing the need for a heavy security apparatus. Now one of the major requirements of maintaining security of capitalist/imperialist interests is to have intelligence on the activities of individuals or groups who may be actively opposing the capitalists/imperialists. So intelligence gathering in violation of individual privacy has been a feature of liberal democracy right from the beginning and it has only got more sophisticated and ubiquitous with the development of technology. Thus, it is not at all surprising that in this age when computers have made possible deep data analysis on a huge scale, this technology will be used for mass surveillance.
The irony in all this is that while the liberal democratic State considers it to be its privilege to collect data on the citizens of the world it criminalises attempts on the part of the citizens to know about its own nefarious activities!! Every liberal democratic State across the world has the equivalent of an Official Secrets Act which criminalises any individual or group that might reveal State secrets. We had earlier the arrest of Bradley/Chelsea Manning and later his/her conviction for leaking official secrets that he had access to as an employee of the US Military, the hot pursuit of Julian Assange for publishing the material that Manning had leaked and now the pursuit of Snowden. The project for liberty which is the core idea of liberal democracy stands completely compromised by this arbitrarily undemocratic behaviour of the liberal democratic State made paranoid by its obsession with securing the interests of capitalism/imperialism. The judiciary which is supposed to uphold the rights of the individual is also hand in glove with the security establishment. When confronted with the uproar over its mass surveillance, the US government blandly stated that these programmes had been vetted by the judiciary. Recently the US judiciary even went to the extent of ordering the sufferers of torture in the Abu Ghraib prison in Iraq to pay the legal fees of their torturers while dismissing the victims' petition for damages on the specious ground that since the matter in question took place in Iraq it was not justiciable in the USA.
Given this kind of restriction on individual freedoms arising from the paranoid attitude of States globally and the huge difference in power between these States and the individuals or groups who are fighting for justice, there is very little hope for the implementation of human rights and the initiation of a just social and economic order despite the many struggles for justice and freedom that are afoot globally. Thus, it is with a realistic appreciation of these ground realities that we must formulate our strategies for bringing about true democracy.
