I think they are saying that part of the calculation a person makes before committing a crime is what is the likelihood that I am caught or seriously injured. In a society that outlaws citizens having guns the chances of serious injury are much smaller than one where say 20% have a weapon. To the extent that CCTV Cameras increase the likelihood of being caught they have the same deterrent effect of knowing that there is a 20% chance your victim is able to defend themselves.
