LE almost got away with Ruby Ridge. If they had managed to kill Randy Weaver the true story would never have come out. How many times has a "nutcase" gotten his "ticket punched" when the only ones left standing are the LE shooters who did it? Do you really believe that 100% of those cases are justified and happened just the way LE says they did?
I have no doubt that LE is sometimes justified, but I have seen enough cover-ups, and seen how hard it is to bring the truth to light, so that I know we only see the tip of the iceberg.
