The old adage that sport and politics do not mix does not quite ring true. When it comes to an event like the Olympics, they can mix too well and with disastrous consequences.
In the 1972 Olympics, 11 Israeli athletes were shot dead by the Palestinian terrorist group Black September.
The lax German security allowed the 8 Palestinians, with bags of weapons, to scale the fence that surrounded the Olympic village.
They then proceeded to enter the Israeli accommodation and take the athletes hostage, threatening to kill them if the Israeli authorities did not organize the release of 234 Palestinians.
In the resulting debacle, including a failed rescue attempt, 11 Israeli athletes, a German police officer and 5 of the Palestinians died.
A while later the Israeli government launched Operation Wrath of God, a massive search to kill the hostage organizers. The Palestinians no doubt responded in kind.
It is worth noting that the following Olympic Games in Montreal lost an awful lot of money.
