Except they're not trumping up penalties, it's just "Pay the fine for Jaywalking or snitch."

In this case the person did a little more than Jaywalking so they're on the hook for more. It's also possible to have information on a criminal act or conspiracy without being an accomplice.

I appreciate the extremely... principled morality of some here, but the law isn't an ethical framework, it's a practical one informed by ethical principles. It's also not a computer program, people are involved who make decisions based on a number of factors ranging from professional and selfless, to careerist and selfish. That's life.

A really easy way to avoid all of this is to stay out of the system, it's not as though he's in for stealing a loaf of bread to feed his starving child.
