I too would consider myself a liberal. I am generally uncomfortable with the idea that judgments about life and death are made by a small section of the elite wearing arcane outfits - too many potentials for prejudice, as has been proved now that DNA testing is more widely available (at least here in the US).
Took a law class once, and was blown away at how little I, and by extension the general public know about the law, how lawyers can manipulate 'truth', and how scary the prospect of being judged by a group of one's peers ....
The other side of me thinks there are plenty enough people on this planet, in fact probably more than is healthy, and that these people just lost their breathing rights by behaving in this way.
I suspect my perception of the level of (in)justice in the world is why movies like "The Punisher - War Zone" are so satisfying ...but only if I was in charge of the world... I don't trust anyone else
