This issue is very serious.
I believe US courts have held there is no reasonable expectation of privacy for celebrities when they are in public places.
In as much the paparazzo may be guilty of bad taste, he is not guilty of violating any laws.
What Obama is doing is called censorship. I believe that means Obama has no respect for the first amendment to the constitution.
So far as President Obama has violated, at least the intent, or directly of the following Constitutional Amendments:
1, 2, 4, 6, 9, 10, and 16
He may also be guilty of treason.
