This "if you shoot the cops before completed scan to receive a LESSER FINE" flawed mechanic needs to be exposed for what it is - ridiculous.
Kudos to the people who discovered it and yes, the reputation loss is increased + angry cops on to you....
But consider its application in the real world:
SCENE: Courtroom
MAGISTRATE: "Willl the defendant please rise. You sir, have been found guilty to be in possession of a considerable amount of prohibited narcotics and have also been found guilty of intent to supply them. Normally, I would be considering a stiff, custodial sentence bordering on the two-digit mark for your crimes. BUT....since you also DREW A FIREARM AND DISCHARGED IT TOWARDS THE ARRESTING OFFICERS, in a manner clearly negligent of the grave harm and immediate life-threatening danger to these aforemention officers....I see no other recourse but to....minimise the sentence to 3 weeks community service. How do you plead regarding this?"
DEFENDANT: "Thats cool, Daddy-o! Nice wig, by the way."
MAGISTRATE: "Less of that you wee nyaff! Ok, I'm running late for going to the <ahem>...social club, but you are free to go. But know this, you little..... ! WE ARE ON TO YOU! And Officer Friendly over there has got a bumblebee in his knickers over this entire sordid matter. So you better watch out, alright?"
DEFENDANT: "No probs, Chief."
MAGISTRATE: "Right, beat it!"
Defendant leaves court and exits the building, a free and happy chappy. Meanwhile Angry Cop takes off after him, waits till he goes into a shop, pulls out an Uzi and opens up full auto on defendant.......
- Maybe I've taken a few liberties making the point

, but you get the jist of it.
20k Fine for smuggling, but if I open fire on Authority - drops to 200?? ............. insanity!
