Holy Cow. They aren't sworn to carry out justice. They are sworn to uphold the law. You make a school boy's mistake of confusing justice with the law. Their word is not gospel, as it gets challenge by defense lawyers all the time. As for a steeper sentence, why them and not judges lawyer and politician who actually make the laws? As for them weaseling out of the charges, people are often charge with numerous offenses and are found guilty of only a few, this was not a uniques situation. If you feel so strongly that they should be held to a higher standard, contact those who make the laws and let them know how you feel. Of course we all know you won't. You'd just rather spew ignorant vitriol
You'll find that you'll see things more clearly if you breath while you type.
