I can see both sides of the argument. Yes, there's a general attitude that more security is always better. However the Rodney King example makes a separate point that Mike may not have intended - that is, that police power can be abused.
If surveillance and other types of technology eventually become a near inescapable blanket of power in the name of security and crime fighting, history teaches us that it can be abused by those in control of it, if they are not held in check in some way.
I guess it's each person's decision as to where they might balance the desire for security against their personal freedoms and rights.
