Specially referring to the British legal system (although others will apply), the system itself is part of the punishment, and is often used maliciously as so. You can be accused of X, have your details leaked to the press (by the police!), have social judgement cast upon you, only to be quietly found innocent later.
From personal experience: Better yet, you can have the police abuse their power to seize property and raid your home during the early hours of the morning, only to have all charges dropped, in which case you have to go through a lengthy process to get your (now damaged) items back. There is zero recourse, all of the oversight bodies are filled with ex-police and look after their own.
Meanwhile the real guilty people are 'let off' (non-pursued) because they flee the jurisdiction of the local police, or are part of a community the police are scared of. They only care for easy quick wins.
To address the article directly, the current system is to let 10 guilty men escape justice, whilst harassing 10 innocent men, and occasionally prosecuting them too.
