John Armstrong blasts the mail order rifle "evidence"

[Albert Doyle]

Instead of all that, why wouldn't Liebeler simply not call the witnesses at all?

Because they had exposed themselves too badly by anonymously tipping-off the Dallas police and Channel 8 - not to mention Dial Ryder himself who was a witness to the planted tag on Saturday morning the 23rd. If Liebeler ignores this it could blow back on him from Channel 8 sources or other sources that then created a controversy over why such incriminating evidence was ignored. What Liebeler did was bold damage control designed to casually dismiss a very dangerous issue that Armstrong has now exposed. By ignoring it and getting caught Liebeler would have risked a John Armstrong popping up at the time and figuring out it was ignored because of all the reasons Armstrong has now exposed. Safer to do a pretend review and dismiss it than risk attracting attention to it by ignoring it.
