It's why we have regulators, judges and magistrates - to apply judgement and proportionality. Sure there's a few headline cases of some absurdly harsh sentence - and just about always the details reveal there were a lot of very damning circumstances that make the sentence seem pretty reasonable.
Do US judges rubber stamp a maximum sentence each and every time? No. Does every visit by police result in prosecution? No. Is every warning and scaling mechanism offenders get in the US expressed perfectly in statute? No. Otherwise you would have fired all the judges as surplus to requirements.
You're just spreading FUD. Understand the legal system in Europe before spreading such rubbish.
