- The radio DJ Gordon Godfrey spoke out against vigilantes.
- When he was still the Metropolis District Attorney, Ray Sacks spoke out against vigilantes like the Red-Blue Blur.
- In the episode Bulletproof and later in the Season 11 comic Smallville: Lantern, it is shown that the police refers to superheroes/vigilantes like Green Arrow and Superman as "capes". This is somewhat surprising, because neither Clark(until he became Superman) or Oliver fights while wearing a cape. The only time Oliver has ever worn a cape in battle is when Oliver pretended to be the Red-Blue Blur in front of Jimmy. However, just like in the real world, in the world of Smallville most comic book superheroes, like Warrior Angel, wear capes. It should also be noted that the time Oliver wore the cape disguised as the Red-Blue Blur was the very first time the existence of the Blur was definitively "proven" to the satisfaction of the general public, making that one time an iconic, unforgettable moment to the normal people of the Smallville universe.
