A Tale Of A City In Four Colors
Bangkok is now developing into battlezone formation. Hoardes of Red PPP supporters are moving into the city centre, outnumbering those Yellow PAD supporters still there. So they beat a retreat to their two airport strongholds. The Brown police has apparently straddled themselves somewhere in between while the Green army still has the entire Bangkok outskirts surrounded.

PAD is a minority group. They mainly consists of elites, middle class who feels Thaksinomics did not benefit them. The days when Thaksin crack down on drugs, he made enemies with drug lords. Some of them are indirectly involved in donations to PAD and PAD warfest
If want to talk about gangsterism, the Red supporters can be more fierce than the ones in Yellow. However when Thaksin was disposed in a coup, they never resort to actions attempted by the Yellow PAD.
