Please do not take this the wrong way.
I am again left wondering on the validity of your statement, i.e. the impossibility of the situation.
How do you know this? Do you honestly think that by just 'killing off' these people, that this action is going to get to the root cause of the problem and forever root it out? Hardly. If there is to be research upon this subject of which I have vast experience in a professional capacity, then surely it makes sense to find the root cause of the problem in order to effect any kind of meaningful solution.
It's not as simple as you state, you certainly would not cure it with your reccommended action by any means. Such writings only serve to stir up actions of vigilantism which is in no-ones overall interest.
It's a very indepth subject with no easy answers, solutions.
If you would like more information, can supply.
