Krioukov based his argument on three factors:
One: because the cop was watching the intersection at an angle, Krioukov’s car appeared to be going faster than it actually was.
Three: a car obscured the cop’s view of the intersection. That means that he couldn’t see Krioukov pull up and stop at the intersection, and assumed he blew through it due to his (incorrectly guessed) high speed.
Not leaving his case on the basis of those three logical points, however, Krioukov went about verifying his theory, calculating acceleration and deceleration rates as well as vision angles and potential speeds. In the end he presented to the judge a mathematical proof that it was possible for the scenario he mentioned to have occurred.
Reportedly, both the judge and the cop who prosecuted him agreed with him, though whether it was because they thought he was right or they were blinded by science is not known.
