Of all the accusations above, the only one that amounts to a hill of beans is the one I highlighted in bold above. If the bikers can show evidence of this one thing, then they have a BIG case against the cops. But, without it, they have little or nothing.
Are you an attorney? I ask because several (including one I can name - Clinton Broden) have asserted that there are more grounds for action against Waco than that one you cited.
