點解警察巡邏叫行咇？

Q:點解警察巡邏叫行咇？
其實不是寫作行咇,而是行Beat,是英語來的
因為Beat的英語解釋就可指警察的巡邏路線,負責區域;故行Beat意思就是在自己負責的區域進行巡邏之意
以下是Cambridge 及Yahoo字典的解釋:
beat (AREA)
It means an area for which someone, such as a police officer, has responsibility as part of their job:
Bob has worked as an officer on this particular beat for 20 years.

beat
(警察等的)巡邏路線,負責區域
The officers know everyone on their beat.
警察認識自己巡邏範圍內的每個人。
