Under the current administration, that will simply be impossible.
And, as a rule, an incoming administration overlooks any illegal or corrupt behavior on the part of the previous administration. Seems to be a "political courtesy", so to speak.
In this case, though, the lawbreaking and corruption has been so egregious, so widespread, so subversive of both our Constitution and a neighboring country...not to mention the direct cause of hundreds of deaths...that it should be incumbent on the incoming administration to a.) complete the investigation and b.) severely punish those responsible.
If, as a nation, we condone this type of behavior on the part of any administration, we are asking for even worse behavior in the future.
Even if Obama pardons everybody, the facts of the case must be determined and fully publicized. The full degree of criminality and corruption must be exposed.
You are absolutely correct. This thing has international connections. Our government cannot cause the deaths of hundreds of citizens in another country without a declaration of war, as I understand it—Viet Nam notwithstanding.
