"Look before you leap!"

Since young we are being thought to "Look before you leap!"  This phrase applies to our everyday lives - before we cross the road we must make sure that the road is clear; as simple as when we go marketing, we must make sure that whatever we want to buy must be fresh before we purchase; children who are intending to further their study must decide wisely what their interest are before they sign in to the course they want to pursue; couples who are intending to get married needs to make proper and wise arrangements for their life-long commitment, etc.... etc..... 

Couple of days ago, I was making my turn as the traffic light turned green at Jalan Tun Ahmad Zaidi Adruce towards Jalan Badruddin.  Then, all of a sudden two traffic police on motorbike drove out at speed from the entrance of the Police Headquarters and made a halt and put their hands up, requesting all on coming traffic to stop instantly, giving way to some police vehicles to exit!

Lucky enough the vehicle behind me is not speeding while making their traffic light turn, or else I will sure get bump into!!  

Is this the right way for police personnel to act??  Is such a protocol so necessary??? Even if it's so, but can't they at least follow some traffic rules so accidents won't have to happen!!  Common sense tells that before you stop any vehicle at any entrances, at least take a look first, if the on-coming vehicles are not too near in making their stop, then do so at your liking, but not if the on-coming vehicle is too near!!  This is what happens when authorities takes the law in their own hands ~ frustrated indeed ~
