The statement's recent place in the public consciousness is largely because it was used as a pro-police slogan against the BLM/"police abolition" movement in the US. The Rust community, being overwhelmingly progressive, is already sensitive about supposed dogwhistles, as well as words that cause them negative associations, in computing (in the vein of "master"->"main" renamings); having that slogan used as a metaphor for keeping out changes that they want in a technical debate would be felt by some of them as an open taunt or provocation.
