//Hong Kong human rights lawyer Mark Daly expressed concern about what he called "a lack of restraint" in using such laws, some of which were "vaguely drafted... without meaningful input from Hong Kong".
There is "a lack of human rights protections for any sense of balance, particularly freedom of speech," he told the BBC.
Rights groups say that the judgment has a chilling effect on Hong Kong society.
Amnesty International's Asia-Pacific regional director Yamini Mishra said that convicting someone for using a "widely-used political slogan is a violation of international law, under which expression must not be criminalised unless it poses a concrete threat.
"The conviction of Tong Ying-kit is a significant and ominous moment for human rights in Hong Kong."//
