He was talking about governmental "security" in exchange for freedom

So was I. The government is the police which is local law enforcement. I can club you and take your wallet more readily if I know the police wont come looking for me.

Look, this guy likes metal detectors but he doesent like to take his shoes off. Thats fine, but its not the big hysteria civil rights connundrum he makes it out to be. Oh, and I notice the obligatory complaint about "racial profiling". Yea, lets pretend humans cant be discerning and rational and un"prejudiced" when it comes to security. Whatever.

Do you REALLY believe that a mugger is going to try to rob you with a policeman standing next to you? The police don't prevent crime, they only take crime reports and arrest the criminal if they catch him, more by accident rather than by design.

In many large cities, the police don't even bother to investigate property crimes

Exactly. The Constitution, both in original intent and in current practice, demands protections that at times limit the efficiency of law enforcement. That's fine. Profiling is one such law enforcement method. But the Constitution does not require the political correctness of banning a person's apparent race from the profile categories.
