All of the above (though the first point doesn't cut it with Barak, or the Euro lot). It is a total mess, armed red shirts are 100m from my appartment, the army 200m away.
The Chinese protesters were not armed, and had not been there for 10 weeks, intimidating all those around them. The cuddly pictures of group singalongs is very one sided.
For several weeks one of my staff has been subjected to physical searches of bags and frankly appalling intimation every time she went home. She couldn't move out because her elderly parents were too scared to move. Another colleague has stopped using his car because he lived in the red shirt area and the car was searched every time, including when he was with his young children. The noise from the protest site has meant that residents cannot sleep at night. No matter the how righteous (or not) the aims of the protest, such behaviour is intolerable and had to be stopped.
