I doubt that those who are making fun of the Thai police and their people-control rods have ever seen them in use, nor have they ever seen a taser used on someone, except in the movies/TV shows. I've had the experience of assisting as a translator, from a safe distance, as several TRP officers, calm and collect out-of-control foreigners with mental health problems, often exacerbated by alcohol and drugs. These people usually respond well to being helped by calm professionals, rather than law-enforcement personnel who seem bent on harming them.
Thai police are so much kinder and more gentle than American police would ever be. A taser would only enrage someone more and could miss or even be turned against law enforcement. The police don't come into direct, crushing body-contact with the person they're detaining with the control hoops/hooks, so little chance of a George Floyd situation. Much more opportunity to "talk down" a situation, even if the soothing voice is in Thai. Sometimes better if an older white woman is talking to them (that would be me).
Frankly, the orderlies at the local government mental hospital can be rougher than the RTP, but they have the option of injecting tranquilizers, which the police don't. The police have to rely on time-tested methods of calming someone out-of-control, like the hoops and hooks pictured several times in this thread and a take-charge attitude with calming voices like you'd use with a child throwing a tantrum or a charging water buffalo. Thais are good at this.
