is one piece episode 589 filler?

Tashigi tells Smoker that if her memory did not fail her, she remembers that recently, there had been numerous occurrence of child abduction. However, Smoker is surprised as he did not know of such matters.

Tashigi explains that when such cases are reported, they are published as “accident at sea” or the “work of pirates”. She trails off, not completing her sentence.

Smoker questions if she is having difficulties saying it and asks her to speak her mind. Smoker voices out, reaching the conclusion that someone in the G-5 unit helped to cover up the abduction cases.
