Assange would be advised to stay away from barbells and accidental gunshot wounds to the back of the head.
Since he is not going out, he’s safe from the murder/robbery that didn’t include a robbery or lingering too long in public parks, a plane crash or a mysterious car wreck.
The Ecudoran embassy should make up a manikin to look like Assange and remotely roll it in front of a window. Sandbag the floors and back walls.
