This is a politic topic, I have been to the muslim area in China this Aug. there has many cameras on the street, this is the fact. But most Muslims working and living well with other guys, they are very kind to others , and have a very small part of them because of bad education, they use violence to ruin the peace of the area, our Gov spent too much money at this place to make it's a safe place. I think the gov is doing the right thing, right now West of China is the safe place, our culture is safe is more important than anything else. Cams just as a tool to watch out the criminal, not weapon.
