Footnote to both of the preceding

Again via the Iraqi Press Monitor, this time the June 2 edition, quoting the daily of the Al-Mada Institution for Media, Culture, and Arts:

In a new way of targeting Iraqi security forces, insurgents have distributed poisonous watermelons to police checkpoints, which resulted in the death of one officer. Nine others were taken to the hospital for treatment. A Defense Ministry official said an unknown seller driving a pick-up truck distributed the poisonous watermelons to six checkpoints.

I've been trying to think of some pithy, fitting remark but other than a bitter reference to "by their fruits ye shall know them" I haven't come up with anything.
