It is, again, the process of the threat assessment. How possible is it, wherever you're doing this assessment, that this threat may happen? It happened in Russia. It happened in Glasgow. In Glasgow, a car full of explosives was driven into the terminal and exploded. I forget the number of casualties. The same thing happened in Madrid in the parking area.
Coming back to Israel, the Israeli threat assessment has a protocol that says cars are inspected in the vicinity of the airport, not while arriving at the airport. So four kilometres before you arrive at the airport, on the highway, you have a kind of checkpoint where they verify whether the car represents a risk or should undergo an inspection. In Israel, this risk exists. In Baghdad, it exists every day, because cars explode every day. How high this risk is here and whether this is an actual risk is up to the regulator to analyze.
In Germany two years ago, a group of so-called homegrown terrorists was preparing bombs from chemicals they bought on the free market. They were detergents. They were caught, luckily, days before execution, but they had exactly the same intention.
It is a question of risk assessment.
