News roundup, 9 Sept 2026

- The crew of the Amazon freighter that overran the runway in Miami on the weekend, killing five people in a vehicle, appear to have dithered on whether to abort their landing and perform a go-around. Investigators have yet to interview the pilots on the matter; I suspect that the pilots are not looking forward to this.

- Mark Carney is warning that there will be a cost for Canada's pivot away from the US, but that the costs of not doing so will be much greater. Carney also mentioned tariffs imposed by William McKinley's administration at the end of the 19th century, which he says were intended to "pressure us into dependence and eventually annexation by the United States". The Trump regime has responded to Canada's counter-tariffs with a ban on the import of motorcycles and alcohol from Canada as well as a series of new tariffs on various other products.

- UK Foreign Secretary Ed Miliband has accused Israel of ethnic cleansing in the occupied territories and has banned the import of goods produced in Israeli settlements in the West Bank. Predictably, his Conservative critic has warned against making Israel a "pariah state" and expressed concerns that the move will somehow lead to an increase in antisemitic violence in the UK (the fact that Miliband is Jewish is an inconvenient fact that critics will ignore, of course).

- Lab technicians and technologists with Dynacare went on strike on Tuesday morning, leading to disruptions in non-urgent diagnostic tests across Manitoba. Labour Minister Malaya Marcelino quickly filed an application with the Labour Board, requesting that the board issue an interim order that the 350 employees remain on the job in order to "ensure the provision of essential health services"; the request was quickly granted. Jason Linklater, president of the Manitoba Association of Health Care Professionals, condemned the move.

- A fatal stabbing in Winnipeg in 2022 was solved after the killer's DNA was found on a beer can in the victim's home. The suspect was subsequently arrested on another matter and confessed to the killing; she has pleaded guilty to manslaughter and sentenced to six years in prison.

The dark side of DNA

In a world where the average juror gets his or her information about DNA testing from sources like CSI, and thus tends to think it to be infallible, stuff like this is scary:

Gregory Turner feared he was bound for life in prison after an RCMP lab reported odds of 163 trillion to 1 that a tiny amount of DNA on his gold ring could have come from anybody but a 56-year-old woman found murdered in rural Newfoundland.

The only real evidence in a first-degree murder charge against Mr. Turner, the golden sheen of DNA appeared certain to become a silver bullet in the hands of the Crown.

"I told my lawyer, Jerome Kennedy, that there was no way in the world it was true," Mr. Turner recalled in an interview. "He believed me. He said that I was too stupid to commit that crime and leave no evidence."

A lucky hunch by Mr. Kennedy - now Newfoundland's Minister of Health - saved Mr. Turner from a life behind bars. He sought the name and DNA profile of every technician who had worked at the RCMP lab. It turned out that the technician who had tested the ring had also been working on the victim's fingernails a few inches away, creating a strong possibility of contamination.

The technician conceded at Mr. Turner's 2001 trial that she had also contaminated evidence in two previous cases. In another disturbing twist, it emerged that she had mistakenly contaminated Mr. Turner's ring with her own DNA, causing police to waste considerable time on a futile search for a presumed accomplice.

Mr. Turner still has nightmares. "I remember the judge saying that he was denying me bail based on the likelihood I'd be convicted based on a DNA match," he said. "I think DNA can be good, but its only as good as the people who perform it. I spent 27 months in jail for a crime I didn't do."

From the Globe. Among other things, advocates of capital punishment should take note of stuff like this.

Police in UK accused of arresting people purely for DNA samples

At least, that's what is expected to be reported at an inquiry:
Police officers are now routinely arresting people in order to add their DNA sample to the national police database, an inquiry will allege tomorrow.

The review of the national DNA database by the government's human genetics commission also raises the possibility that the DNA profiles of three-quarters of young black males, aged 18 to 35, are now on the database.

The human genetics commission report, Nothing to hide, nothing to fear?, says the national DNA database for England and Wales is already the largest in the world, at 5 million profiles and growing, yet has no clear statutory basis or independent oversight.

The highly critical report from the government's advisory body on the development of human genetics is published as the number of innocent people on the database is disclosed to be far higher than previously thought ‑ nearing 1 million.

The commission says the policy of routinely adding the DNA profiles of all those arrested has led to a highly disproportionate impact on different ethnic groups and the stigmatisation of young black men, with the danger of their being seen as "an 'alien wedge' of criminality".

The crime and security bill published last week by the home secretary, Alan Johnson, proposes to keep DNA profiles of people arrested but not convicted of any offence on the database for six years. This follows a landmark European court judgment last December, ruling illegal the current blanket policy of indefinite retention of DNA profiles whether or not the person has been convicted of an offence.
From the Guardian. Hell, why don't they just take a sample from everyone at birth? Oh yeah, it's not white folks' DNA that they're after...
