It's called detaining without cause, and it's illegal, policy or not.
If I park my car behind yours in a parking space, because it's convenient for me, and you want to leave (and can't), what's your next act going to be? Think.
I can't believe I'm siding with pills (SL) on this issue, but he's right.
The only disagreement I have here is that I don't believe "common people" are "stupid".
I think there's an extreme lack of common sense in the world, and once people really investigate this matter (and others like it), they'll see that this really is an issue that shows some hypocrisy...
Where's the outrage here? Why is it the people who believe they should be able to do as they please (smoke pot, enter same-sex marriages, perform abortions) are not up in arms about something like this?
Attention Lefties: This is an example of Corporate America taking away your rights. If it was the Patriot Act, you'd be having a hissyfit.
I'm "outraged". Unfortunately, our fellow NICOnauts called me names for being so. As an example "conspiracy theorist".
Did you see my post about the new trial going into place in Philadelphia? I will quote the article for those that don't wanna click on the link

Software used to predict who might kill
By Michael Matza

PHILADELPHIA - University of Pennsylvania criminologist Richard Berk, a trained statistician, never met a data set he didn't like.
Now, using fresh data from the Philadelphia probation department, Berk and three colleagues have built an innovative model for predicting which troublemakers already in the system are most likely to kill or attempt a killing.
With the homicide rate in Philadelphia outpacing last year's by at least 7 percent, a computer model for "forecasting murder" is in the works, Berk said, to be delivered to the probation department in the new year, with clinical trials of the new tool to begin in the spring.
Initial research suggests the software-based system can make it 40 times more likely for caseworkers to accurately predict future lethality than they can using current practices.
The project is funded with a private grant and the software is in the public domain, so the product will be delivered to the city free.
"This will help stratify our caseload and target our resources to the most dangerous people," probation department director of research Ellen Kurtz said. "I don't care as much about (targeting) the shoplifter. I care a lot about the murderer, obviously."
Sociologists have produced hundreds of studies using discrete pieces of information about offenders to try to come up with the means to identify probationers most likely to commit future felonies.
But homicide, because it is a relatively rare event, has been very hard to predict. Of all probationers in Philadelphia, only about one in 100 will commit homicide. But for obvious reasons it is crucial to find that needle in the haystack, Berk said.
Though it is well known that the probability of becoming a killer falls off with age, especially between 18 and 30, Berk's innovation is that he uses the relatively new statistical technique called "step-function" analysis to show how fast and when the dropoffs occur.
"In reality the risk doesn't decline in a smooth, straight line" but falls precipitously at certain points for certain reasons, he said.
The tool works by plugging 30 to 40 variables into a computerized checklist, which in turn produces a score associated with future lethality.
"You can imagine the indicators that might incline someone toward violence: youth; having committed a serious crime at an early age; being a man rather than a woman, and so on. Each, by itself, probably isn't going to make a person pull the trigger. But put them all together and you've got a perfect storm of forces for violence," Berk said.
Asked which, if any, indicators stood out as reliable predicators of homicide, Berk pointed to one in particular: youthful exposure to violence.
Using probation department cases entered into the system between 2002 and 2004, Berk and his colleagues performed a two-year follow-up study - enough time, they theorized, for a person to reoffend if he was going to. They tracked each individual, with particular attention to the people who went on to kill. That created the model. What remains at this stage is to find a way to marry the software to the probation department's information technology system.
When caseworkers begin applying the model next year they will input data about their individual cases - what Berk calls "dropping 'Joe' down the model" - to come up with scores that will allow the caseworkers to assign the most intense supervision to the riskiest cases.
Even a crime as serious as aggravated assault - pistol whipping, for example - "might not mean that much" if the first-time offender is 30, but it is an "alarming indicator" in a first-time offender who is 18, Berk said.
The model was built using adult probation data stripped of personal identifying information for confidentiality. Berk thinks it could be an even more powerful diagnostic tool if he could have access to similarly anonymous juvenile records.
The central public policy question in all of this is a resource allocation problem. With not enough resources to go around, overloaded case workers have to cull their cases to find the ones in most urgent need of attention - the so-called true positives, as epidemiologists say.
But before that can begin in earnest, the public has to decide how many false positives it can afford in order to head off future killers, and how many false negatives (seemingly nonviolent people who nevertheless go on to kill) it is willing to risk to narrow the false positive pool.
"If we have 100 probationers I can accurately find the one murderer who statistically will be in that group if I devote resources to all 100 as if they are murderers. The problem is that for that one murderer who is a 'true positive,' I have 99 false positives. We all would agree that's not a good use of resources.
"Now suppose I can identify the 10 at highest risk. For that one true positive I now have nine false positives," Berk said, "and that may be something we choose to live with."

Its purpose is to use the precog(nitive) potential of three genetically altered humans to prevent murders. When the three precogs, who only work together, floating connected in a tank of fluid, have a vision, the names of the victim and the perpetrator as well as video imagery of the crime and the exact time it will happen, are given out to the special cops who then try to prevent the crime from happening. But there is a political dilemma: If someone is arrested before he commits a murder, can the person be accused of the murder, which - because of the arrest - never took place? The project of pre-crime, at the time being in a state of trial run, is going to be voted about in the near future. If people accept it, the crime rate is going to drop drastically, but it never will be known if there might not be too many people imprisoned, some or even all of them innocent. After John Anderton lost his son to a crime a six years ago, he took up drugs, and works the precog division like nobody else. One day, his own name arrives in the "perpetrator" chute, and the precogs predict that he will kill a man he never knew in less than 36 hours. John takes off, his trust in the system diminishing rapidly. His own colleagues after him, John follows a very small trace that might hold the key to his innocence, a strange unsolved yet predicted murder and a so-called "minority report", a documentation of one of the rare events in which a precog sees something different than the other two.[/quote]
