There's a good article about Sinn Fein in the Irish Examiner by Fergus Finlay in which he accuses them of abusing their mandate.

"They seem to have entirely forgotten the Proclamation of Independence by which they claim to set so much to store.The call to arms in that document ends by calling on republicans to ensure that "no one who serves that cause will dishonour it by cowardice,inhumanity, or rapine."

Well said,Mr Finlay.You can read the article in its entirety here.
