Wrinkles just wondered why you chose these two examples:

"As to the Irish terrorists always giving warning and not going for as many random casualties as possible; two words; Enniskillin and Omah. No-warning bombs, placed in localites that would only harm random civilians, have been a feature of the NI Troubles since the 70s."

Was it because of the number of people killed as in the Omagh bombing? Or was it becaude these bombs were carried out by Republicans. The PIRA in the former and the Real IRA in the other.
