Airport got check ah!

Even the layman taking the bus to the airport is now been checked!

Or has it always been this way? But when I take the cab, it arrives infront of the glass window of the arrival or departure halls and no one ever asks me to open my bag or check if I'm carrying anything suspicious...

Then why do they do it to buses or vehicles that enters the basement of the airport terminals?
If I cant bring forbidden stuff through the basement, I'll just do it via other ways.... not very smart leh....

got loopholes, must plug them!
