On the positive side, it's a progress check for the people, this way there are no hidden secrets, no media to infuse the truth with bias and inconsistent sourcing. Every live document featured is directly from the government. For example directly from the war logs, we can detect inconsistencies with the civilian body count in Iraq. Since October the published figure of 109,000 recorded civilian deaths has been corrected by wikileaks to 150,000+. Easily one of the largest military leaks in history. Wikileaks also bolstered one of the Bush administration's biggest claims of Iran playing a part in the Iraq war.
The only issue I can fathom is that the freedom to view these kinds of leaks can be dangerous, we cannot predict how people will use this information. Hypothetically, holes in the airport security system can be identified directly from the security handbooks that they leak, even though this organization does not leak this kind of information, aside from privatized government corporations, what risk would lie in exposing this kind of political information?
