His PA police force, including the general who heads it, has been directly involved in a terrorist attack against Israel. This is the answer to those who suggest that Arafat is doing his best. Terrorist attacks, in any event, don't take place on the spur of the moment. They need a logistical infrastructure to prepare, package, and deliver explosives to the killers, who have to be recruited and trained. Potential targets have to be surveyed.
Suicide bombers have to be housed, fed, and transported to the scene of the crime.
All of this requires many participants over an extended period. It does not strain logic to suspect that such aid has come from some of Arafat's many security services and his 40,000-member police force. It has to be conceded that the terrorists enjoy the support of the Palestinian people. And the stench of hypocrisy is high. Arafat's office maps of Palestine include all of Israel, including pre-1967 Israel.
