The legislation was quick to achieve one of its main aims — ending the protests.
The first arrests came on July 1, the anniversary of Hong Kong’s return to China and just one day after the law was enacted.
As crowds defied a ban on protests, police moved in. Most of those arrested under the new law were carrying or shouting pro-independence and pro-democracy slogans.
Hong Kong’s government announced that the popular protest chant “Liberate Hong Kong, revolution of our times” breached the new rules against inciting secession.
Another visible imprint of last year’s protests also came down. So-called “Lennon Walls” — murals of pro-democracy art and messages erected in many shops and cafes, and on roadsides — were widely removed.
No large-scale protest has broken out since July 1.
