Do you know Why Markhor is a symbol of ISI?

Markhor is the national animal of Pakistan and the official symbol of ISI. It may be due to two reasons. One because of national animal and second it has the same objective of capturing and killing snakes of Pakistan who are hidden under the cover of being Pakistanis and Muslims. These snakes keep on hiding in their holes and are in contact with lethal foreign cobras to whom they worship. But whenever they see Markhor, their heart stops with his dread. This is the reason they say that if something bad happened to them it will be because of Markhor (ISI).
