In Canada, in part because police forces have been cautious and measured in adopting this technology and are using it in relatively limited ways, I do not know of such examples.
In the United States, where the uptake has been faster and less cautious, our sister organization, the American Civil Liberties Union, currently has litigation in several states fighting for men—all of them Black—who were misidentified by this technology. One in particular, Mr. Williams, had police come to his home, handcuff him and drag him out of his home in front of his minor children.
