Demonstrations against the bill began in March and April, but escalated in June. Hundreds of thousands of people marched in protests of the bill on 9 June. Protests on 12 June, the day the bill was scheduled to a second reading in the Legislative Council, marked a sharp escalation in violence. Riot police deployed tear gas and rubber bullets against demonstrators. Subsequently, investigations into police behaviour and greater accountability for their actions became part of protestor demands. A larger march occurred on 16 June.
Protests continued through the summer, escalating into increasingly violent confrontations, between police, activists, pro-Beijing triad members, and local residents in over 20 different neighbourhoods throughout the region. 21 July marked the infamous Yuen Long mob attacks against protesters and bystanders.
As demonstrations continue, protestors are calling for an independent inquiry on police brutality, the release of arrested protesters, a retraction of the official characterisation of the protests as "riots", and direct elections to choose Legislative Council members and the Chief Executive.
The inclusion of mainland China in the amendment is of concern to different sectors of Hong Kong society. Pro-democracy advocates fear the city's jurisdiction would merge with mainland Chinese laws administered by the Communist Party, thereby eroding the "one country, two systems" principle established since the 1997 handover. Opponents of the current bill urged the Hong Kong government to establish an extradition arrangement solely with Taiwan, and to sunset the arrangement immediately after the surrender of the suspect.
