《刑事罪行條例》第60條一問, 為何摧毀或損壞屬於其本人的任何財產即屬犯罪? 自己打破自己個杯都犯法?

1. Yes - (2)(b) is the key.

2. Because they are not related.

For example, you break dishes on a public street. Even you are not aiming anyone (hence, no assault/battery against anyone), still the destruction of the dishes can still cause injuries to others regardless intent.

The purpose of the section is to "eliminate" the element of assault/battery.

照法律就係。不過無人告你。

打到別人或是故意吵到別人。影響到他人安靜生活的權益，就極有可能。敘述只截取自己可能要得到的答案；也犯法嗎？誠實都知道那可稱獨斷。
