The MO of using a motor-cycle borne terrorist to beat access control has been followed by terrorists in many countries, including Pakistan, for the last 30 years. In the past, terrorists using this MO used either a hand-held weapon fired by a terrorist sitting in the rear or a hand-grenade. When a hand-held weapon or a hand-grenade is used chances of success are not always guaranteed unless it was a suicide attack.
In the case of magnetic bombs stuck to the metallic portion of a car by a speeding terrorist, chances of success in killing or maiming targeted individuals increase without adding to innocent civilian casualties.
The Israeli diplomat attacked was a high-value target of the terrorists, but not a VIP protectee. She, therefore, did not enjoy the benefit of access control through the use of pilot and escort vehicles. It was easy to attack her from a motor-cycle.
Is it possible to devise new security procedures by which high-value targets of terrorists, who do not enjoy the benefit of VIP protection procedures, can be better protected? This is a question which needs to be examined by our security experts.
