Traffic-enforcement cameras have been a common sight in Davenport for 13 years, but now the city is using new cameras for a different purpose: to help prevent and solve violent and property crimes.

Davenport in the past month has begun a pilot project with 18 cameras at four intersections on Washington Street south of Locust Street. The city purchased the cameras for nearly $54,000 as part of a larger neighborhood-revitalization program that also includes street and sidewalk improvements.

The idea is to see to what extent the cameras prevent crime, and how much they assist police in solving crimes that do occur.

But police surveillance cameras, in general, are not particularly good at deterring crime. They can be effective in certain circumstances, but not in the way Davenport is using them.

The U.S. government remains the greatest threat to our freedoms.

The systemic violence being perpetrated by agents of the government has done more collective harm to the American people and our liberties than any single act of terror.

Police body cameras are all the rage lately. Al Sharpton wants them used to monitor the activities of cops. Ann Coulter wants them used to "shut down" Al Sharpton. The White House wants them because, well, they're a way to look both "tough on police violence" and "tough on crime" by spending $263 million on new law-enforcement technology.

When Al Sharpton, Ann Coulter, and the president of the United States agree on anything, my immediate, visceral reaction is extreme skepticism. In this case, the known facts support that skepticism.

(Editor's note: According to a recent article in the The Dispatch/Rock Island Argus, Hampton, Illinois, recently began using body cameras, and the Davenport, Bettendorf, and East Moline police departments have either tested them or plan to acquire them.)

It's exceedingly unlikely that widespread use of police body cameras would reduce the incidence or severity of unjustified police violence. We've already seen the results of numerous technology "solutions" to that problem.

The introduction of mace and Tasers to police-weapons inventories encouraged a hair-trigger attitude toward encounters with "suspects" ("suspect" being law-enforcement-ese for "anyone who isn't a cop"). Their supposed non-lethality made it safer to substitute violent action for peaceful talk.

The introduction of military weaponry and vehicles to policing hasn't produced de-escalation, either. Quite the opposite, in fact: Now we get to watch small-town police departments stage frequent re-enactments of the Nazi occupation of Paris in towns across America.

And police-car "dash cams"? That's obviously the most direct comparison. But the dash cam often seems to malfunction, or the police department mysteriously loses its output, when a credible claim of abusive police behavior arises.

On the other hand, it's absolutely certain that widespread use of police body cameras would increase the scope and efficacy of an increasingly authoritarian surveillance state.

The White House proposal calls for an initial rollout of 50,000 cameras. Does anyone doubt that the output of those cameras would be kept, copied, cross-referenced, and analyzed against law-enforcement databases (including but not limited to facial-recognition databases) on a continuing basis?

Assuming a camera attaches to a particular officer with an eight-hour shift (rather than being passed around at shift changes for 24-hour use), that's 400,000 hours per day of random, warrant-less searches to be continuously mined for probable cause to investigate and arrest people. Even George Orwell didn't go so far as to have 1984's Thought Police carry portable cameras everywhere they went!

Video technology is certainly part of the solution to police violence, but that solution should remain in the hands of regular people, not the state. More and more of us every day come into possession of the ability to record video on the spot, while instantly porting it to Internet storage so that it can't be destroyed at the scene or tampered with after the fact. Cops need to be on cameras they don't control.

But part of the solution is still just part of the solution. Even when cameras catch violent, abusive, criminal cops in action - as, for example, when business security cameras filmed Fullerton, California, police officers Manuel Ramos and Jay Cicinelli beating homeless man Kelly Thomas to death in 2011 - it's incredibly hard to get prosecutions and even harder to get convictions.

Ubiquitous video monitoring of state actors by regular people is a start. But the only real way to guarantee and end to police violence is to bring an end to state "law enforcement" - in fact, to the state itself.

Every regime has its own name for its secret police. Mussolini's OVRA carried out phone surveillance on government officials. Stalin's NKVD carried out large-scale purges, terror, and depopulation. Hitler's Gestapo went door-to-door ferreting out dissidents and other political "enemies" of the state. And in the U.S., it's the Federal Bureau of Investigation that does the dirty work of ensuring compliance, keeping tabs on potential dissidents, and punishing those who dare to challenge the status quo.

Whether the FBI is planting undercover agents in churches, synagogues, and mosques, is issuing fake emergency letters to gain access to Americans' phone records, is using intimidation tactics to silence Americans who are critical of the government, or is persuading impressionable individuals to plot acts of terror and then entrapping them, the overall impression of the nation's secret police force is that of a well-dressed thug, flexing its muscles and doing the boss' dirty work.

It's a far cry from the glamorized G-men depicted in Hollywood film noirs and spy thrillers. The government's henchmen have become the embodiment of how power, once acquired, can be so easily corrupted and abused.

"A standing military force, with an overgrown Executive, will not long be safe companions to liberty." - James Madison

"Here [in New Mexico], we are moving more toward a national police force. Homeland Security is involved with a lot of little things around town. Somebody in Washington needs to call a timeout." - Dan Klein, retired Albuquerque Police Department sergeant

If the United States is a police state, then the Department of Homeland Security (DHS) is its national police force, with all the brutality, ineptitude, and corruption such a role implies. In fact, although the DHS's governmental bureaucracy may at times appear to be inept and bungling, it is ruthlessly efficient when it comes to building what the Founders feared most - a standing army on American soil.

The third largest federal agency behind the Department of Veterans Affairs and the Department of Defense, the DHS - with its 240,000 full-time workers, $61-billion budget, and sub-agencies that include the Coast Guard, Customs & Border Protection, Secret Service, Transportation Security Administration (TSA), and Federal Emergency Management Agency - has been aptly dubbed a "runaway train."

Time to buckle up your seatbelts, folks. You're in for a bumpy ride.

We're hurtling down a one-way road toward the Police State at mind-boggling speeds, the terrain is getting more treacherous by the minute, and we've passed all the exit ramps. From this point forward, there is no turning back, and the signpost ahead reads "Danger."

Indeed, as I document in my book A Government of Wolves: The Emerging American Police State, we're about to enter a Twilight Zone of sorts, one marked by drones, smart phones, GPS devices, smart TVs, social media, smart meters, surveillance cameras, facial-recognition software, online banking, license-plate readers, and driver-less cars - all part of the interconnected technological spider web that is life in the American police state, and every new gadget pulls us that much deeper into the sticky snare.

In this Brave New World awaiting us, there will be no communication not spied upon, no movement untracked, no thought unheard. In other words, there will be nowhere to run and nowhere to hide.

We're on the losing end of a technological revolution that has already taken hostage our computers, our phones, our finances, our entertainment, our shopping, and our appliances, and now it's focused its sights on our cars. As if the government wasn't already able to track our movements on the nation's highways and byways by way of satellites, GPS devices, and real-time traffic cameras, government officials are now pushing to require that all new vehicles come installed with black-box recorders and vehicle-to-vehicle (V2V) communications, ostensibly to help prevent crashes.
