Help Me Understand This

Let's see, now:

Car bombs kill people.
Car bombs kill people by exploding in proximity to crowds of people.

So, if cars cannot come close to crowds, cars rigged as bombs cannot kill and maim those crowds when they explode. Or, am I just all wet?

Is there something ungraspable about this?

OK, now for some tougher questions.

Why are cars in Iraq allowed near police academies, police stations, the green zone, markets, schools, and any other places where people congregate?

Why can't Iraqis walk from Park-and-Frisks?

Now, to the toughest question of all: Why is no one in the Sunni Triangle learning from the car bomb experience?

***

I shall next have to contemplate why Iraqis in the Sunni Triangle seem not to care to be blown up in stockyard lots.

These questions are really tough.
