I also would not want to be the LEO standing at the phone booth waiting for the call to come in. (Next target?)
They had gotten "Tip line" calls from pay phones in the area, and the nubmer they were given (in the message) to be called on was also in that area. But I agree, no way was the sniper, or the leaver of the note and/or the tipline caller would use a phone in that area. Much policework depends on the bad guy being dumb, as most of them are, but this guy or these guys are apparently not.
