I think you are right about the rebus.

At first I was sceptical about the JLo = MAL letter
but it's beginning to make a certain peculiar sense.

I think you are right about the rebus.
At first I was sceptical about the JLo = MAL letter but it's beginning to make a certain peculiar sense.

Notice that this theory makes the contents of the J-Lo letter essentially the same as the other anthrax letters: it has the 09-11 date (the rebus), and it has the "Death to Israel" threat (the Star of David in either anthrax powder or dust).

"A certain peculiar sense" is a good way to put it.
