M B Jerusalem's bomb squad, the most experienced in the world, hits the street up to 100 times a week. Its sappers are on the front lines of terror in the Holy City. s, SW E AT 8t TE A RS EDWIN BLACK - Special to The Jewish News F or an instant, there is no street, no crowd behind police barriers, no world, not even a sense of time. There is only Yoni and a large plastic yellow bag atop an illegaly parked BWM in the middle of downtown Jerusalem. Just a man and a package. Yoni is a member of Jerusalem's elite Bomb Squad, the most experienced amd field-tested bomb squad in the world. As he studies the suspicious yellow shopping bag, Yoni's face suddenly tightens. Riming to his partner, he mutters, "I think it's real." They immediately begin what the squad calls "an attack." Yoni's partner, aided by policemen, clears the street. Motor traffic is directed away. People emerging from doorways and around corners are shooed back. During those same seconds, Yoni races to his white Dodge van. He swings open the side panel door, adjusts the shiny .45 automatic hugging the small of his back and straps on lightweight velcro-tipped protective clothing: A flak j acket, leggings, and a thick crotch protector. Jogging back to the yellow bag, he dons his heavy helmet and dense plastic face mask to complete the ensemble. Minute one has elapsed. Yoni's partner has already laid out the equipment. Yoni begins deploying a special device at various points in the vicinity of the bomb — some as far away as down the street. Neither the device nor any of the squad's sophisticated techniques can be described. Specially designed by the Jerusalem bomb "sappers," "the device" is the squad's initial counter-measure. Yoni must now attach a "gadget" to the bag. He approaches again, gaze transfixed. Backstepping, he makes a final check of the vicinity. "Wait!" his partner yells. A woman carrying a baby has just turned the corner and walked near the yellow bag. Yoni waves her down: "Get back." As soon as she sees his green bomb protection suit, she fades from sight. Minute two has elapsed. The street is finally clear. Yoni crouches behind a pillar, but if that bag is packed with explosives, it will maim anyone within 20 yards. Pillar or not, that means him. Now fear comes to Yoni, not as an enemy, but as a companion. A pause. A thought. He activates the anti-bomb "device." The package is suddenly "neutralized." Minute three has elapsed. Yoni grins through streams of sweat. "For a while in the beginning," he says, "we are always afraid. But then it comes out okay, and we feel fine." As Yoni collects his gear, and the street quickly returns to nor- mal, people in the crowd can be heard
