Suppressor (Silencer) Fitted Rifle in the Dal-Tex Building?

[Bob Prudhomme]

Some of the witnesses, at least, were able to identify gunshot noises by the muzzle blast, because they would have been too far from the path of the bullet to hear the much-less-loud subsonic crack. I am reminded, that the first report heard by many ear-witnesses was misidentified as a firecracker, which seems less likely if the full muzzle blast noise was also present. The problem with the "echo theory" explaining why 20 cops converged on the grassy knoll, is that Chief Curry ordered them there...and since Chief Curry was on the opposite side of the target from the most likely shooter(s), the supersonic crack would have originated from north-ish and reverberated from the overpass itself, not the fence on the knoll.

Do you agree, Bob, that there is good evidence for more than one type of weapon being fired?

Hi Drew

You have to understand that I am only discussing the first shot as being from a suppressed rifle. The last shot does not seem to have been from a suppressed weapon, and Curry, or someone near him, may have heard this shot from the Grassy Knoll. If you recall, a motorcycle cop was supposed to have raced up and given him the news of the shooting. Could this cop have been near this last shot?

What makes you believe the bystanders on either side of the street were too far away from the path of the bullet to be able to hear the "crack" of the sonic boom? If you watch the video I posted, you can hear the sound of the sonic boom returning from down range for several seconds. These witnesses would have heard the "crack" plus the echo of it as the bullet passed by every vertical reflective surface near its path. These witnesses, seen in Altgens 6, could very well have heard the "crack" without showing startle reactions, simply because the sonic boom is not as loud as a 140 decibel muzzle blast. However, any muzzle blast at all would have given away the location of the shooter. As there were, in 1963, suppressors capable of eliminating 100% of a muzzle blast, I'm willing to bet there was no muzzle blast from the first shot.

Yes, there were different weapons being fired in Dealey Plaza that day. Several witnesses reported that the last shot was much different than the first.
