The "faux rifle" man in Towner03 is mentioned here ( Link ) and a crop of the figure was featured in the 1993 Robert Groden book "The Killing of a President". They're serious about it.
I have a copy of "The Killing Of A President" and appreciate many of the images in that book. It's author, Groden, is another pusher of that guy/kid standing on a cement pedestal on Towner 3. Whether intentional, accidental, and/or due to sheer incompetence, Groden has been a huge distributor of JFK Assassination disinformation which he continues doing to this day. I believe his biggest transgression among many is his splicing together of assorted JFK Assassination footage. This has created all kinds of confusion as to exactly who filmed what and ensuing Line-Of-Sight issues. Groden through his slicing and dicing of assassination film footage managed to shroud the work of Darnell, who is only now beginning to gain the recognition he merited for his 11/22/63 assassination filming of Houston St, Elm St, the Elm Ext, the top of the triple underpass, the train yard, the area between the picket fence and the short wall, and the exterior of the TSBD. In short, anything proffered by Groden has to be looked at closely.
