Also remember China does not have a real bail system. If you get arrested, you are very likely end up in prison directly. You also can be disappeared (better than be suicided) during the process.

Also, Chinese police has a habit of using force to rob the corpse of the victim from the family who want to send the corpse to the 3rd party for examination. For example: https://en.wikipedia.org/wiki/Shishou_incident
