The extradition bill would allow officials to send suspected criminals to mainland China to be tried. Critics of the bill argue Hong Kong residents would be subjected to unfair trials and worse legal protections in the mainland.
Human rights groups have expressed concern about China's use of torture, capital punishment, and arbitrary detention within the legal system.
Critics of the extradition law also call out Hong Kong's chief executive, Carrie Lam, for a lack of leadership over the unpopular legislation. Lam introduced the bill in February after a Hong Kong resident murdered his girlfriend in Taipei before fleeing back to his home city, and since tweaked the bill after pressure from the opposition.
Some critics from Hong Kong worry China has already begun overstepping on the city's legal system. A Hong Kong billionaire mysteriously disappeared in January after being into custody in mainland China. A bookseller connected with publications that criticize the communist regime also went missing, before revealing he was taken into Chinese custody.
