Police brutality have nothing to do with LY brawling. You have Police brutality cases in USA, ROC, and every other country on the planet.
One needs to address the issue of why doesn't the PRC annual congress meeting doesn't end up in a fist fight.
There is something wrong with ROC democratic process if it allows these type of individuals to be elected into office in the first place.
Just by citing that ROC is has direct elections for LY members and PRC has a republic system for their congress is not enough to allow this type of behavior to continue.
I find this reasoning to be misleading. If it made every political and social decisions based on how the USA would have conducted itself, it would be useless to ROC, which maybe part of the problem on Taiwan in general. A German based political system with USA reforms is what ROC has now.
I do agree with you that ROC needs to learn from other governments. However, I beleive they need to take a hard look at Singapore and PRC, and how their political counterparts conduct themselves to gain international respect. Especially Singapore, which is even smaller than Taiwan, yet has so much more political capital than Taiwan on the international theater.
