The other day I was on the tennis court alone, practicing my serve. From nowhere I heard a sudden loud noise, like an explosive. I couldn’t make out the source but then I noticed a flattened can on the other side of the court, about fifteen feet way. I went over to investigate and found a squashed can of corn beef hash, full, heavy. It had evidently been dropped from above the court, at least twenty floors up (the building has 44 floors and faces the tennis court). The act of dropping it had clearly been intentional and the purpose was presumably to scare me. If it had hit me on the head, it would certainly have killed me, such was the power of the impact. Reflecting on the incident later, it occurred to me that this was a minor act of terrorism: the purpose was to infuse an ordinary, peaceful activity–playing tennis–with fear and anxiety. And it worked: since that day I am always looking up and the calm of my tennis has been replaced with a kind of dread. Terrorists have made even the quotidian and tranquil into a zone of fear. Boy, would I like catch the person who did it. There is something nauseatingly sinister about the terrorist intention: to remove peace of mind.
