"Interpreting Kellerman's words as a flurry of shots coming into the limo indicates more than one shooter." It's entirely reasonable for Kellerman to have used this phrase to describe a situation in which one shooter (Oswald) fired three shots in a matter of seconds striking two individuals in the car.
This would be a reasonable interpretation if you hadn't read Kellerman's testimony.
If you have read his testimony, not only is it an unreasonable interpretation of his words, it is beyond reason.
In reality Kellerman had already described JFK hit by the first shot and states that while he was talking into the radio to get the out of there the "flurry of shells" came into the limo. He is describing a very intense moment that occurred while he was talking into the radio.
Kellerman's words have to be interpreted in the context of the rest of his testimony and any physical evidence relating to those words. Doing this really limits the amount of reasonable ways there are to interpret his words.
