All you need is a vehicle, and anybody can get hold of one of those
with no suspicion at all. Or you could just steal one, a practice that
has been commonplace for many years. It's difficult to imagine any
security measures that would eliminate this risk without rendering the
entire concept of motoring completely useless. A garage full of
homemade bombs would make their intended use pretty clear, but there's
nothing about a lorry or a van that tells you anything about what some
religious nutter might do with it.
The solution (which will not be adopted) is to intern all suspects.
Try to define it, in this context, without defining it as "any brown
person who speaks Arabic", because that will get you into trouble with
those who guard free speech against the right to use it.
