Pickpockets

In Great Britain of centuries past, pickpockets were routinely hanged at public executions. Meanwhile, pickpockets routinely operated in the crowds of spectators. Obviously, what was happening on that platform did not impress them much. They did not get the message or the lesson no matter how powerful the delivery. If you think of those "90 percent" futures and options loss statistics as financial public hangings, vast numbers of speculators are likewise unimpressed until they themselves go to the gallows.
