In case people want to know why letting law enforcement use DNA companies’ databases without warrants, subpoenas, court orders, etc. is a bad idea, here’s a great reason – China Uses DNA to Track Its People, With the Help of American Expertise: https://www.nytimes.com/2019/02/21/business/china-xinjiang-uighur-dna-thermo-fisher.html. Now, before you say it could never happen in the U. S., Canada, Australia, Japan, Europe, or other places that have some form of democracy or representative republic forms of government, history is full of examples that show otherwise.
From the article:
The Chinese authorities turned to a Massachusetts company and a prominent Yale researcher as they built an enormous system of surveillance and control.
I find it hard to believe this quote was meant seriously given what we know of the Chinese government although based on the way he said it, he meant it seriously:
Dr. Kidd said he had been unaware of how his material and know-how were being used. He said he believed Chinese scientists were acting within scientific norms that require informed consent by DNA donors.
Good to see the Massachusetts company is no longer providing equipment:
On Wednesday, Thermo Fisher said it would no longer sell its equipment in Xinjiang, the part of China where the campaign to track Uighurs is mostly taking place. The company said separately in an earlier statement to The New York Times that it was working with American officials to figure out how its technology was being used.
