I guess it depends on where you live. When I lived in Palm Beach, I could walk back and forth over the bridge to West Palm without a problem. But if I had been a black man, I would have been stopped by the cops. (I saw them stop severl black men who were walking over into Palm Beach, none looked like likely criminals).
The Palm Beach police once pulled over a guy in an SUV outside my room, and I wish I had had a videocamera on me then. I watched them search his vehicle (he had been pulled over for going through a stop sign), and as they stood there more cops showed up. They asked him if this was his vehicle, he said no it was his mom's. They asked if that was his mom's gun in the glove compartment. He said he never saw it before. They also found a bag of weed. He claimed to have never seen it before either. Two of the cops laughed and high fived each other behind the SUV, then their faces went back to being serious as they came around the corner.They took the weed and the gun and let him go with a traffic ticket.
I myself was stopped by the cops in Palm Beach just for walking at night. I told them my car was parked behind the Everglades Club where I worked, and they were extremely sacastic in asking me if they called there would they get confirmation I worked there. When they discovered I was telling the truth, they did not apologize they just left.
So, do we live in a police state? I think so, and I think its our own damn fault for buying into what the media has been saying about how bad crime is. Crime is no worse now (overall) than it was 20 years ago. Again, it makes a difference where you live, but I think its because the media has made us afraid to even say "hi" to our neighbors, it has made us rely on a larger and larger police force to make us feel safer.
More and more cops out there means they have to justify their existence, so we are going to be pulled over more often and harrassed even when we are completely innocent. This applies to the TSA mentality of treating everyone in the country as a possible terror suspect, equally. I mean after all, its the only way to be "fair" is to treat everyone as a possible criminal.
