I can't tell you all but among them:
- Using the murder in Taiwan as a pretext to introduce the bill when it could easily have been handled ad hoc with Taiwan.
- Claiming it was a loophole left over by the British when it was very clearly by design.
- Initially refusing to suspend the bill in the face of huge opposition.
- Taking months to fully withdraw the bill and proudly ignoring the protestors.
- Blanket refusing an independent enquiry and unwaveringly supporting police no matter how brutal and unprofessional they've become.
- Seeking permission from Xi to withdraw the bill.
- Introducing an anti-mask law instead of attempting serious reform.
- Threatening internet lock downs instead of attempting serious reform.
- Not criticising the central government for threatening military violence and flagrantly manipulating coverage of HK on the mainland.
Those are just a few that stand out to me though I'm sure there are more I've missed.
