What makes it good agitprop is that she's 13 and the cops didn't give a fuck, it shows their inhumanity. And idk, if china holds people for weeks or months without a hearing I'd be critical of that too, generally. Not all lib "evil CCP must go" levels of mad about it, but certainly it's not ideal.

Edit: they did give her a bail hearing. so feel free to scratch the bit about "without trial nor hearing" It was cash bail though, and it still feels like the word "homeless" was all it took for the jailers to give zero shits and throw away the key

edit 2: ultimately what people are mad about IMO, is the fact that they felt scolded for posting about this here, which is you know, not a mixed space and not primarily/solely for agitprop. The phrasing was some shit people harboring liberal opinions about police love to trot out.
