Woops?

Police don't usually prevent crime except passively. People tend not to do criminal things in sight of the police.

Their primary work is coming in after a crime has already happened and cleaning up the mess in whatever manner is needed.

Hello sfdi1947.
I find your comment a bit condescending. One does not need to be in law enforcement to understand their work or how they perform it. A citizen has a right to an opinion regarding how every public servant operates and making their job easier is not criteria sufficient to deny citizens a means to oversee and observe that function, nor to be warned of their presence. This technology could be abused, like any other, but it also has advantage as the article points out of having most users check their behavior and thus improve safety for all. The police can't prevent crime. They can only come in and clean up afterwards. The only way one might argue that they can prevent crime is by making their presence known (high visibility), by driving the roads and walking the beat, not by sitting behind a road sign waiting to pounce like a thief in a dark alley. How did we ever get by before LEOs had the use of electronic technology... when we were all on even footing? I do not blame the Cops generally who are only doing their jobs as directed. I blame the officials that set the policy and force police to be revenuers instead of peace officers.

Truckers have been using their radios for years to warn others of police presence. How is this different?

And, as far as if you are "not doing anything wrong" you have nothing to worry about... this flies in the face of all of the wrongly accused, incarcerated and those whose property has been confiscated through forfeiture laws without due process... mistaken identity and many other factors come into play.
Police are imperfect humans also. They are not all angels. "If men were angels, no government would be necessary." - James Madison
Respectfully,
O.A.

yes, police work for my city, my state, my federal government. Citizens have a right to expect that their government will work within the Constitution. History has shown that government is the most dangerous when it's given too much power, not criminals

You have faith?
I don't think you've spent enough time in here to tell us what we're "all missing".

If you don't understand the Constitution perhaps you shouldn't comment. As a matter of fact, I AM the first one to complain if some cop nut job goes off and people like you do nothing to prevent it. what you ignore is that more and more, the government IS the criminal. It's the whole point of the Constitution-4th Amendment?

minus 1 for ignorance and telling me not to comment on your ignorance

Faith sounds like religion, not reason.

Sounds as if you could stand a little refreshing of the actual work 'of law enforcement'. For myself, I don't want cops out there trying to 'prevent' crime. I want them doing their jobs of picking up the true criminals, like the bankers and politicians that crashed the economy.

I do understand the work of law enforcement, and kh is correct.

Huh?

Tell that to the people in Wisconsin that had their doors broke in, computers and other stuff confiscated in predawn raids at gunpoint because they made political contributions to political parties that the left wing did not like. Below is a link to an interview one of the people gave about the ordeal if you care to listen to what happens when law enforcement gets out of hand.

Bull S$$t. What country do you live in?

If they want to pull you over, they will find SOME thing to pull you over for...... do you seriously believe there is no elements of power mongering going on within the police force? Just because too many Americans don't know their own Constitutional rights doesn't mean the cops should abuse their 'power' via intimidation tactics just because they get away with doing it.
Should a person walking down the street with an AR 15 slung over his back be harassed by police?

"as you say, you're not doing anything wrong, they will leave you alone"
If this statement were true and some humans were paragons of virtue, we could give them unlimited powers to investigate and punish crimes. Unfortunately, humans are flawed. We create institutions with checks and balances that try to overcome those flaws.
