I agree with you tbh. Considering the tremendous false positive rate with sniffer dogs too, I find the use of them especially hard to justify as anything other than intimidation. Got to remember though that when police do big operations like that, they may also often be looking for one specific target/individual, but have to use a blanket approach to apprehend them. So while you may be caught up in the "random" checks, they may just be using it as a facade to catch a truly dangerous person.
