Bombs are nasty

Stuck to a garden door near my workplace. I'm not at all sure who would go to the trouble of designing, printing and posting this little paper banner, and I've no idea why they thought it was worth the trouble. We all know, of course, that the political profile of Sinn Fein is badly compromised by the party's old associations with paramilitary groups. But why have a shot at SF now? And why lay on the irony with a shovel? All this is is a bit of tiresome undergraduate sarcasm. Anyway, why do I bother even to notice...
