Blackwater thugs show total disregard for human life and have killed many people in broad daylight in Iraq [nighttime activities are a whole new can of worms].

US army does something big in Afghanistan? No problem. However, both Pakistan and Afghanistan should strongly oppose deployment of Eric the Devil's Blackwater in Afghanistan.
Blackwater's level of expertise in combat is Special Forces level (they actually hire Special Forces veterans) and these thugs can operate virtually kind of weaponry including nukes (American sources).
"Like it or not, Blackwater has technical expertise that very few companies do have. And they have a willingness to work in places that very few companies are willing to work. So they provide a much-needed service and the ability to do it well." - Geoff Morrell
Eric the Devil is drawing parallels with East India Company for making inroads into Afghanistan. No, thank you.
UN have also ruled against use of organized mercenaries in warfare (United Nations Mercenary Convention).
