The change in movement made me look more human but my proportions exactly matched the other SecUnits. I was good enough to fool humans who weren’t looking for me, since humans tend to ignore non-standard behavior in transitional public spaces. But anyone who had set out to find me, who was alert to the possibility of a rogue SecUnit, might not be fooled, and a simple scan calibrated to search for SecUnit size, height, and weight was certain to find me.
