"When a conservative think tank in Nevada last month suggested mandating that teachers wear body cameras to ensure they don’t teach critical race theory," writes Sidney Fussell, "I thought it was ridiculous, offensive, and entirely feasible." After all, schools in the U.S. are already massively surveilled because of school shootings. One company even "floated the idea of pinging administrators whenever teachers searched words like 'strike' or 'union.'" But that's no guarantee that they'll prevent teachers from teaching about critical race theory (CRT). No doubt teachers could find ways to get around the proscription on free speech and reasoned debate. Body cameras been used by police to misrepresent their encounters with the public.
