The US system have far too severe penalties. Sentences of 10-100 years are now common. Conditions in prisons are horrible with rampant drug abuse, violence and even murders.
However, the Swedish prosecutors and courts are banana republic quality. Look at the Assange parody for an example. A Swedish prosecutor may invent almost anything as evidence, even a photoshopped screenshot - because ANYTHING can be submitted as evidence in a Swedish court. There is even a recent drug case where the Swedish police illegaly put GPS surveillance on a suspected drug trafficker. The court recognizes the police did this illegaly, but the GPS data is still allowed as evidence. This is called "fri bevisföring" in Swedish. The courts are made up by politically chosen representatives, not a jury, which further contributes to the banana republic sentencing.
So - justice is more blind in Sweden, but she is slapping you on the wrist, instead of decapitating you.
