I think in these days of increasing globalization, litigation funding may be a necessary evil. If you consider the difference in power between a massive multinational and individual consumers/citizens its a little frightening. A good tort lawyer is not enough to give you a fighting chance. You need something as big, bad and ugly on the other side of the line who can fight just as dirty to force a settlement. Yes some lawsuits are frivolous but others most certainly are not ..and we still lose them. Think about the tobacco litigation in the states.
As for the police, you would have to be terribly na?ve to think that police are not capable of corruption. I am very supportive of the police and think that they generally do a very difficult job very well, but there are bad apples in every walk of life and blind, unquestioning support is dangerous in my view. Of course police action needs to be subject to review and supervision.
