Given the sensitive nature of the bill, and its timing, and She has shown her understanding in how US / China / HK operate in both Financial and political levels.

I find it hard to believe all of these are incompetence and coincidence. Not saying Carrie Lam is a CIA agent, but something is definitely not right.
