Making an example out of someone to send a message to others is completely unjust for the person who is made an example.

Did they intend the crime? And their only defense is "The other guy was doing it too"? Oh well.

As long as we prosecute as many people in their position as possible it doesn't seem to be a problem if we miss some. It's only selective when we choose who to ignore.

Something like Aaron Schwartz where it wasn't a crime until someone who made the DA look like an idiot does it... Then it's clearly crossed the line.
