Billboard Advertising Banned Products In Russia Hides If It Recognizes Cops
m.alessandrini writes: In response to a ban of food imported from the European Union, an Italian grocery in Russia hired an ad agency to create a billboard with a camera and facial recognition software, that's able to change to a different ad when it recognizes the uniform of Russian cops. Gizmodo reports: "With the aid of a camera and facial recognition software, the technology was slightly tweaked to instead recognize the official symbols and logos on the uniforms worn by Russian police. And as they approached the billboard featuring the advertisement for Don Giulio Salumeria’s imported Italian goods, it would automatically change to an ad for a Matryoshka doll shop instead."
The reason this sentence is bad is because it's a so-called garden path sentence.
You parsed ‘banned’ as the main verb with subject ‘billboard advertising’ but in fact ‘banned’ is a participle acting as an adjective to ‘products’.
These sentences are called garden path sentences because they lead you along the ‘garden path’ which seems neat and kept and trimmed on both sides until it turns out to be a dead end and you should have taken a left somewhere.
