Translation of "ezinezko" into English

Horrela poliziak ezin zuen bilera desartikulatu, eta norbait atxilotzen bazuten, agian bilera bertan behera geratuko zen, baina ezingo zuten bileraren lekua topatu, eta ia ezinezkoa zen norbait atxilotzea nahiz eta filtrazioren bat izan.

That way the police could not disrupt the meeting, and if they arrested someone, the meeting might be canceled, but they would not be able to find the place of the meeting, and it was almost impossible to arrest someone even if there was a leak.
