The Israeli infiltration into Hamas must be pretty good. Capturing and trying them in court, especially if it was the World Court, would be better. If a PA police and court would do that it would be ideal. But we know that wouldn't happen at present. But such a time can come.
From today's (8/13/01) New York Times:
Four Hamas members were reportedly arrested by the Palestinian Authority over the weekend, including a man said by Israel to have been the one who sent the pizzeria bomber on his deadly mission. But the arrests were waved off by Israeli officials today as too little too late.
PA can't win for losing.
