No, it's a perfect analogy for those who say that velocity, not energy kills.
We live in a society that practically revolves around speed and velocity. How fast do you walk? How fast is the speed limit and how much can you push it and not get a speeding ticket? How fast are airplanes?
Velocity or speed is easy to measure. When driving, you constantly check your speedometer to see how fast you are driving and can you speed up or should you slow down. We understand speed.
The velocity of a bullet can easily be measured by a chronograph. Reloading manuals give velocities for different weights of gunpowder. Cartridge manufacturers state the velocities of their bullets on the cartridge boxes. Many reloaders have a chronograph. We understand speed.
Physics tells us that every moving object has kenetic energy, and that kenetic energy is calculated by multiplying 1/2 of the weight of that object by it's velocity squared. We can't see the energy, we have to calculate it, and most people don't want to be bothered with doing the calculations, so they just fall back on the thing that they somewhat understand which is velocity.
