CNN | Pauline Chiou | Acid attacks are 'easy' in Hong KongThere will always be concentrations of people outside of security cordons, and those people will always be vulnerable to bombs, bullets, fires, corrosive chemicals, electrical currents, falling objects, mean people with pointy things, fast moving chunks of tubers, and all manner of other stuff. It's silly to rope off a tiny portion of our public space and attempt to secure it.
Hong Kong, China (CNN) -- Another mysterious acid attack took place during the weekend in Hong Kong. It was the sixth such incident in the past year.
The target is always a crowded street full of shoppers and the weapon of choice: plastic bottles filled with acid.
Preemptive investigation and rapid emergency response, people. That's all that will protect us.
