In all fairness The president is not the chief of police in Sandy Hook, and if my memory serves was not present at the school when it happened. He, like almost all of us, have to rely on third party information. Our courts have a name for this type of information; heresay.
For that reason I think it a bit over the line to accuse him of lying.
The accusation of using the tragedy to further a political agenda may be accurate. However, this is coming from both sides of the issue.
Is it too much to think that our elected president may actually be acting in accordance with what he believes to be the right thing to do?
Whether one agrees with him or not, if he is following his beliefs that is much different than "lying".
Don't get me wrong, Obama isn't my favorite president right now, but making accusations without basis is not the right thing to do. Seems like I vaguely remember that being one of the ten commandments for you people of faith. I am going to go out on a limb and say that not bearing false witness is an ideal the secularists can agree on as well.
