Obama could not be prosecuted for the felony crime in the courts in the first place.
The most they could do would be to name him an unindicted co-conspirator and go ahead and convict the other people who participated in the felony.
It would be up to the House to indict him (that's what impeachment is) and the Senate to convict and remove him.
Once the Senate has removed him from office, then we can go back to the court proceedings and formally indict him and convict him before a judge and jury for that felony.
What would happen IF an authentic and legitimate birth certificate surfaces which proves Obama was born in Kenya?
Where does that take this nation constitutionally?
What happens to Obama legally?
O.K. I get the scenario. If a POTUSA were to openly or by preponderance of evidence known to shoot, knife or by whatever means commit murder, POTUSA would have to be impeached and removed from office before being tried before a jury of his/her peers for the crime of murder. This seems to be a convoluted procedure for justice and not how the ‘common’ person would be treated. I don’t believe a POTUSA with the public and political support of a person as for Obama would ever be impeached and removed from office for whatever crime and as such is shielded from equal justice. The King is almighty.
