Bitter ‘Milkman’ Issue Again Haunts Bugliosi

How is citing allegations against Bugliosi a response to the allegations against Lane? The post is about Lane not Bugliosi.
If someone posted allegations against Bugliosi and the response was to cite allegations against Lane or Garrison or Salandria would you think that's a response to the Bugliosi allegations? No, you would see it's a dodge, an attempt to change the topic. Which it would be. Just like what you are doing.
More important, Bugliosi was not going around the country for decades accusing people of murder and conspiracy. Very serious charges. Essentially treason. Lane was doing all of that. He spent decades screwing up college kids minds with his lies and falsehoods. It's Lane's credibility that is the question not Bugliosi's. And there's a long, long series of serious allegations - not just this one - that were made against Lane.
And despite your efforts, this *does* go to the credibility of a person, of their integrity and honesty. Do you think person "A" with a series of questions about their honesty is just as credible as person "B" with no questions about their integrity? Everyone is going to be more skeptical of person "A" then "B". Rightly so.
