Your laptop will be detained at the border, without reason, forever

The Washington Post does a nice job of translating DHS policy

The policies state that officers may "detain" laptops "for a reasonable period
of time" to "review and analyze information." This may take place "absent
individualized suspicion."

into plain English:

Federal agents may take a traveler's laptop or other electronic device to an
off-site location for an unspecified period of time without any suspicion of
wrongdoing, as part of border search policies the Department of Homeland
Security recently disclosed.
Also, officials may share copies of the laptop's
contents with other agencies and private entities for language translation, data
decryption or other reasons, according to the policies, dated July 16 and issued
by two DHS agencies, U.S. Customs and Border Protection and U.S. Immigration and
Customs Enforcement.

Nevermind that any of this data can be transferred just as easily over the internet (which I highly advise for all travellers, btw), this is a scary and stupid policy. DHS is one-upping other sectors of government in the 'arbitrary and indefinite detention' genre by not even requiring suspicion to detain items. Michael Chertoff is the most dangerous man in America and needs to be stopped. Thank goodness there are a select few people in government (Sen. Russell Feingold, mentioned in the article) that still care about the Bill of Rights. See also Schneier's post.

Crossing the border? You're a terrorist!

From the Washington Post via Slashdot: It seems as though the federal government has hatched yet another brilliant idea with which to invade Americans' privacy. The culprit is another data-mining and analysis mega-project aimed to screen everyone who enters and leaves the country for a potential terrorist threat.

In a round-the-clock operation, targeters match names against terrorist watch lists and a host of other data to determine whether a person's background or behavior indicates a terrorist threat, a risk to border security or the potential for illegal activity. They also assess cargo.

Each traveler assessed by the center is assigned a numeric score: The higher the score, the higher the risk. A certain number of points send the traveler back for a full interview.

Yet another opportunity for bigoted assumptions about the nature of terrorists and bad data to act as an excuse for the government to expand its power. A little imagination reveals what the scoring system might look like:
+5 points if an Arab
+5 points if you are under 30
+5 points if you are dark-skinned
+5 points if you are wearing a turban
+5 points if you have no intention of returning to your home country
... and so on ...
+5 points if you look at the border officer the wrong way
+5 points if you assert your rights as a U.S. citizen
+5 points if you have recently attended a peace rally
+5 points if you have ever spoken against any policy of the political party in power

But, of course, DHS et al feel no accountability to any individual citizen, just like their no-fly (and other) lists. Once you've been marked as a terrorist (however apocryphal that label might be), just try getting off of it:

According to yesterday's notice, the program is exempt from certain requirements of the Privacy Act of 1974 that allow, for instance, people to access records to determine "if the system contains a record pertaining to a particular individual" and "for the purpose of contesting the content of the record."

Scary.
