Report: Too Soon
A team of scientists from Virginia State University conducted the study over the course of several weeks, and determined that it is still too soon. The team suggested waiting several days, or perhaps several weeks, and checking again, but given the sensitivity of the matter, they cannot offer reasonable odds on it not still being too soon even after that much time has gone by.
An earlier study hinted at it being too soon, but was focused on the details of the incident and not on the rhetoric surrounding it. The Virginia group decided to examine specifically whether it was time yet, and began collecting data that would help them reach a conclusion.
Analysis of the data pointed conclusively to there being not enough of an interval between the unfortunate events and the specific kind of discussion related to it. Commenting on, or joking about, the event in that manner would prove hurtful to many people, and it is therefore recommended to refrain from such treatment of the event at least until the initial wounds have had time to heal. Ideally, say the researchers, more than a year should pass before another attempt is made to determine whether expressing the notion would still be insensitive.
