Just to play Devil's Advocate - it is not technically a violation unless they stop you from doing something. Merely noting it and maybe announcing it to the rest of the World is not a violation.bigstones wrote:The answer to your question is that when the government does it, it is a violation of your freedom of association guaranteed by the First Amendment. The First Amendment establishes three important rights freedom of speech, freedom of religion, and freedom of association.SoftwareEngineer wrote:The real problem is this. There is a lot of activities that are near the edge of legality. For example taking or buying drugs, paying for sex, owning and shooting guns, looking at pictures of naked people, and in particular using high-capacity magazines for handguns. The reason they are on the edge is that they are common and have long traditions, but are considered unseemly and are despised by many. In particular by anti-fun anti-libertarian nosy people who like to control other people's behavior. Note that these are all "victimless crimes" (perhaps with the exception of prostitution, although someone who of their own volition enters into a "rent my body for an hour for money" contract is perhaps a victim, but definitely a willing participant in a civil contract).
We can't outright prohibit these. It has been tried over and over (the 18th amendment is the ultimate example of a train wreck caused by do-gooders). So instead we try to regulate and curtail them. And in doing so, we tend to lose our common sense of what is appropriate and sensible. This leads to a silly war on drugs (which creates real crime, lots of murdered people, oodles of needlessly incarcerated people), shaming of both sex workers and Johns, incredibly complicated and mostly ineffective gun control laws, and a porn industry that is highly profitable. The most ridiculous example is the insane situation of high-cap magazines in California: You can own them, but you can't buy new ones, you can repair certain damage to it but not other, they can be confiscated without just compensation if they're considered a nuisance (even though owning and using them is not a crime), and you can't drive through LA with them, but it's OK to drive around LA.
The extant case is one more example where the "righteous indignation" caused people to do something that's just dumb. Publicly shaming John's is expensive, divisive, borderline unethical (I'll explain why below), and probably completely ineffective. It makes politicians look good to a certain segment of the population (those people who are rightfully upset about the collateral damage from prostitution, and religious fundamentalists who are against all forms of sex), without accomplishing anything.
If our society could only become more clear in its thinking about these problem areas, and make them either completely illegal and enforce, or make them completely legal, the whole problem would just go away. But no, we can't do that, because there is a conflict between a vocal minority of prohibitionist crusaders, and a silent majority of people who have all these distasteful habits. And a democracy doesn't work well if the majority feels that it needs to be silent, because it is ashamed.
Now, why is using plate scanners "unethical"? Because, as pointed out above, our society as a whole (not just government!) needs to learn to respect privacy more and more. And government should lead there, instead of being dragged by activists into following. The correct reaction of the LA city government should have been: Yes, we have license plate scanner data (and surveillance cameras, and cell phone location records). Yes, we need to collect it, for law enforcement, city planning, and such purposes. We are not willing to help anyone in their pseudo-moral crusade against activities (such as driving a car in an area known for prostitution) that are inherently not illegal. And because we are unwilling to help with such crusades, we have arranged our data retention policies such that neither the city government as a whole nor its individual staff are even capable of doing so. That's why we chose to store plate scanner data only in abstracted, summarized and anonymized form for the long term. Whatever data we have, you can have, but you're not going to be able to figure out from it where John Doe was on the night of January 16th.
Instead, this thread turned into a rant against government (evil), big data (more evil), and citizen's united (most evil), all of which is wrong.
My 2 cents.
