The post you linked has been removed and the thread repeatedly debunked this claim. It's an old video that pre-dates the incident.

It's more relevant to point out the shoddy construction and failure to control number of persons on the bridge than to blame those who drowned. If a bridge collapse because a few people jumped and shook the wires it wasn't sturdy to begin with. Why are you and your friends at the sub you linked not holding the govt accountable? Wasn't it repaired four days ago? Why instead are you showing an old pre-repair video and trying to pass it off as the cause?
