Are Americans dying because of White House inaction Brian Terry died for President Obama's sins?

I would like to point my finger at all who are at fault. Obama, Janet Napolitano, Congress, employers who illegally hire illegals. Before them it was Bush Jr, Michael Chertoff, Clinton, and Bush Sr. That's who I blame. If everyone of them had never allowed human and drug smuggling to become such a profitable business, we wouldn't have this mess.
