You're missing the point.
This isn't about the public at large sticking the metaphorical two fingers up at the murderers.
What you explain in this context is quite correct.
However, the question is whether it is appropriate for a business to use an event like this as a method to promote its operations. Remember the context. Not a week since the act, not all murdered identifed (and to this we can add, many still in hospital).
