Update | 'Bring children to pee in Hong Kong': Mainlander starts campaign after public urination clash
Call for action may break mainland law; call of nature may cost HK$2,000

Internet users calling on mainlanders to let their children relieve themselves in Hong Kong streets - in protest at this week's photographing of a toddler doing just that - have been warned they could end up in trouble, along with anyone who takes part in the protest.
Mainland law prohibits encouragement of such disruptions of public order even if it takes place elsewhere, a veteran lawyer with experience in both jurisdictions said yesterday.
The warning came as controversy continued to snowball over the incident in which a video of a mainland couple allowing their toddler to urinate and defecate on a busy Mong Kok street was posted online.
Solicitor Thomas So Shiu-tsung said Articles 290 and 291 of the mainland criminal code outlawed "assembling a crowd to disrupt social order" and "assembling a crowd to disrupt order of public places".
Article 7, meanwhile, allowed the state to punish citizens who commit such offences outside the mainland.
"It depends on the size of the activity," So said. "If there are only a couple of people turning up, it is unlikely that amounts to an offence."
