Actually claiming that the aircraft was shot down by a gatling cannon which doesn't even exist is miserably weak.
Plus if you had a clue about aircraft and weapon systems, you'd know that a burst of cannon fire from a moving jet wouldn't be able to concentrate the hits to just one small area under cockpit window and the damage area would not only be spread across a larger area of the aircraft but also different to obvious shrapnel damage shown on MH17
