Royal Thai Police Force Ranks

[Thules]

I often see reports on TV that Major-General xxxxx of the Royal Thai Police force attended the scene of a break-in, assault, or whatever. Two things struck me (no, not literally )...

Why would such a high ranking policeman respond to such a relatively minor and common incident ?

How did Thailand historically evolve with police ranking names that are so similar to its millitary equivalents ?

Hope some of you can advise, thanks.

The British police ranks that exist today were deliberately chosen so that they do not mirror British Military ranks, due to public concern about military intervention into civil disorder.
