...since they’re not violent nowadays
I mean that depends entirely on how one defines 'not violent'. The organisation is no longer a participant in a civil war and has destroyed the weapons it used back when it was, but, well, things of a different nature continue and along the way limbs are occasionally smashed.
A PSNI report (take it obviously with a pinch of salt) said that the Military command of the PIRA are still selecting leaders in the North (and that was demonstrated at the latest attempt to challenge Michelle O'Neill). Not sure how the SF inner party workings present themselves in the South.
