Gardaí hitting the middle and lower ranks as a tactic to flush out gang bosses

Insiders suggest there are more important issues: The significance of the people arrested (whether they are so-called gillies or major players), whether the operation uncovers a new form of smuggling (such as inside a car engine, as happened recently) or smuggling route, and if the seizure is an isolated success or one of a series of interceptions.
More important is whether or not the seizures are part of a wider strategy to hit all activities of the particular gang — such as arrests and prosecutions for murders and attempted assassinations and investigations targeting their wealth and money-laundering activities.
