This leads me to believe that he does not possess the ability to do so,
Yes he has. A Ecilpso-Superman. He stole his speed and knocked him out with a lightspeed punch.
The Flash can simply run around his opponent really fast creating a vacuum to suck out all the air from an opponent. Even Quicksilver can do it.
The Flash shutdown an opponent's (Dr. Light) neural impulses by actually temporarily stealing speed from the neural impulses for a picosecond rendering him unconscious.
It's extremely easy for the Flash to make sonic shockwaves. In JLE #6, he snapped his fingers and knocked out a superhuman with a mini sonicboom. Imagine what a clap or a hundred claps can do.
I mean no offense, CC but from your previous posts on this and other threads it seems you base your arguments solely on the recent JLA vs. Crime-Syndicate storyline and the starnet-database which is severely outdated (90's). You should read some of his comics. I recommend the Geoff Johns storylines and the Mark Millar storylines. It shows how powerful he can be.
