I don't know, her explanation was that it's a literal translation from a swedish idiom. There's apparently a swedish idiom which translated literally means "put them up against a wall" with the connotation of meaning "hold them accountable". The same way we have sayings like "hold their feet to the fire" or "rub your nutsack against their face until they finally are willing to stick their tongue out"...
Now, unfortunately, I cannot get past the noise in the searches right now to see whether this is a common phrase, but it passes an initial sniff test. Seems likely this literally was just a direct translation error, and she is speaking from her own words.
