Being a president is a big responsibility they have big burden on their shoulders. Some people, when they are under pressure seems to make wrong decisions and they should not be held up for it. If a sport players makes a mistake during the game and gets away with then I don't think why not the president. But on the other hand president have to be careful because their decision matters more then anyone else.
It seems like this negates the check and balance of the 3 branches of government. The law of the land...Except if you know or it you are agreed with or if you appear. The law is the law and all are suppose to be equal under the law. Justice is blind... Unless.
Nobody should be pardoned for their crimes. Do not commit the crime if you can't do the time. Rich people are the only ones who get pardoned anyway. Pardoning serves no positive purpose to the citizens of society. Criminals will always be criminals regardless of what the president says about it.
