The most grave issue is that each recording likely amounted to a serious criminal offence. Under Irish law, the recording of a telephone conversation on a public network without the consent of at least one party to the call amounts to an "interception", a criminal offence carrying a possible term of imprisonment of up to five years. [...] Consequently, unless gardai were notified that their calls might be recorded then a large number of criminal offences are likely to have been committed by and within the Garda Siochana itself.

It is interesting to note that the fake UK network was the only one detected by Verrimus. However, given that IMSI Catchers operate multiple fake towers simultaneously, it is highly likely that one or more Irish networks were also being intercepted. Very often a misconfiguration, such as an incorrect country code, is the only evidence available of an IMSI Catcher being deployed when forensic tools are not being used to look for one.
