Good comparison.

But whether there are political motivations or not, if there is an appearance of potential wrongdoing then it is in the best interests of America and its citizens and institutions to appear to investigate fully.

Much better for transparency to appear to take everything seriously than to sweep anything under the rug.

If at the end of the process no wrongdoing is found, then all parties can feel good about the outcome.

If wrong doing is found, then a good thing it was investigated.

What you don't want to do is look the other way for fear of seeming to have it in for somebody.
