As another former hunt saboteur, I'd like to bring attention to what Douglas Hogg (fiercely pro-hunting Tory) said about hunt saboteurs in a parliamentary debate about terrorism:
Douglas Hogg wrote:For example, the hunt saboteurs ... threaten serious violence to property. Incidentally, they threaten serious violence to individuals as well.
I strongly disapprove of all those characters, and I am glad to say that existing criminal law covers, in almost every respect, their activities. However, if I ask myself whether they should be treated as terrorists, I am bound to say, no way.
So even the tories (and this was at the height of their power) refused to label hunt saboteurs as terrorists. (Hogg goes on to say why he believes so, it's all a bit long-winded, but very well argued - you can find it here:
clicky)
So why attempt to label hunt saboteurs and animal rights activists as "terrorists" now?
Why would the government want to re-label (i.e. spin) their political opponents as terrorists, especially at a time when everyone is extremely fearful of terrorism and many sectors of the public will ignore incursions on civil liberties when they're told it's "for their protection". (clue: the answer's in the question!)
