A zoo kangaroo excited because there's one loose from his cage. Zoo officials managed to catch the kangaroo and return to his cage. Realizing kangaroo can not jump, finally authorized officer adds that the previous high fence 1 meter to 2 meters. The next day was still able to exit the kangaroo enclosure.

So the salary budget had swelled but did not finish the problem of corruption.
