Why this foot-dragging?

The alleged Rab officials of Narayanganj seven murder case are not arrested yet. Rather it seems that the law enforcing agencies are wasting time deliberately. Why don't they take some effective steps to arrest the trio? The High Court has already ordered their immediate arrest. One wonders if the law enforcing agencies are giving them time to flee. We want those Rab officials arrested right away.
