EastSouthNorthWest contrasts ‘perp walks’ and media coverage of the accused in China, Hong Kong and the US. If you enjoy privacy, Hong Kong is likely the best place to be arrrested.:

The photo with the hoods came from Hong
Kong.  There are two considerations. First, these individuals are only
suspects who are presumed to be innocent until proven guilty, and they may yet
be acquitted.  The hoods are there to protect their privacy.
Secondly, they may have to go through a police line-up to be
identified by witnesses, and showing their faces may contaminate the
identification process.  These points do not appear to be considered in
mainland China.

The FEER’s Travellers’ tales blog, meanwhile, notes that trials in democratic Northeast Asia have much in common with trials in China.:

If you were falsely accused of a crime, would you prefer the trial be held in:
A. China
B. South Korea, or
C. Japan
Give up? The correct answer is D. None of the above.
That’s because in all three countries, the conviction rate is 99%. You have virtually no chance of being acquitted, because prosecutors have incredible power over the trial process and judges trustingly assume the prosecutors wouldn’t have brought a case if they weren’t sure the accused was guilty.
