Man did so many wrong things, helped terrorists to launder millions of dollars and this is the punishment for him? If you live in the USA and declare slightly wrong income, you might face prison. In Germany, at least in Bavaria, police is very strict, you steal chocolates in a row from supermarket and you might go to prison for up to five years. I'm dead serious.
I will tell you this although it’s different in most countries but once you see an elite been fined first after committing a crime then know that he would be get lesser punishment than a Normal Citizen. For this case of CZ I think he might have a very good legal practitioners (he surely did) that actually knew that if he pleaded guilty early enough he would be getting a lesser sentence when court later gives his verdict. I had definitely wondered why he actually accepted guilt earlier and stepped down from his position. I think this less sentence was the reason why.
