The term Wang wang if your not familiar is the noise made from the sirens from things like Police vehicles. Since Aquino has taken power he has begun a crackdown on its illegal use. If you live in the Philippines you will notice the arogant abuses sticking on the sirens and lights pushing their way up the road as if official vehicles but in reality its normally just abuse of power or the fact they are wealthy and assume they can get away with it. I think part of the problem for them now is President Aquino has experienced being pushed to one side himself by these types of people which is why the national crackdown has begun. It will no doubt annoy a lot of people who believe they are above the law but I hope its a sign of things to change and improve the Philippines into a more democratic and fair country. Instead of having money means the law pretty much is useless to prosecute which is part of the plague of corruption. Off to a head start in a way that shows NoyNoy puts the people first lets hope this is a momentum here to stay.
