Perhaps a distinction should be made between real trades, such as those which might be made by most of us, and high-speed front-running trades which can be bracketed with this gentleman's spoof trades which are not really trades at all. The front runners effectively steal from us by distorting the market to our disadvantage, and in my view this should be illegal. The spoof trades rely on misrepresentation which may well be a crime and should indeed IMO be tested in a court of law. It would be interesting to see how the plea of theft from a thief goes down. More to the point, where or from whom did these huge sums of money really come from? I fear it was us.
