You would be absolutely wrong.
There is too much evidence. There are target killers recovered from inside MQM's HQ, coupled with video footage of them inside during the raid, there were illegal military-grade weapons recovered from inside 9-0, there were unreasonable amounts of cash recovered from their offices in Britain and there is an ongoing money laundering investigation. Not to mention multiple confessions that corroborate with the evidence and other confessions, among dozens of other things.
Some of that evidence may be refutable. But In its entirety, the case is solid.
