The pot of money Peter Murrell pilfered from was NOT comprised solely of SNP members' money. It came from three chief sources.
(1) SNP members - subs, donations etc.
(2) UK taxpayers, the vast bulk of the SNP's income.
(3) Non-SNP donors to the "ringfenced indyref fund".
All of that money was swept into the SNP coffers, from whence Murrell trousered it. Every pound he took came in part from each of those sources. So in fact he robbed ALL of us, not just SNP members.
The fact that the party has spent the *entirety* of the "ringfenced" indyref fund, on stuff that is not a second indyref, is an entirely separate issue over and above Murrell's crimes.
