Chief Executive Carrie Lam Cheng Yuet-ngor needs the utmost wisdom and courage to placate Hongkongers dissatisfied with her governance. The unprecedented turnout for Sunday’s rally proved the extent of unhappiness and resentment, necessitating a far-reaching response. An apology given by the government on her behalf as the march neared its end was a day late and, even though it was better than none, far from sufficient. Immediate measures are needed to calm tensions and ensure Hong Kong has the order and stability it requires to confront the difficulties faced.
