These pictures were found on our Contribute page, but we don't know who took them, where exactly this was in Shanghai and when the photos were taken. We also received the following tip on the page from the anonymous poster, which includes a quick translation:

Those protesters pictured here got the CRACKDOWN from Shanghai police. I saw it walking home from lunch. The lady was sobbing and refused to leave. Not screaming because she was mad, but like she had lost the will to live. I wonder what really happened to her son. The stuff on her shirt says:

"Shanghai police arrested my son, then hid his death from me, and won't tell me what they did with his body"
