It's analogous to police "searching" a homeless person by throwing, tearing up and destroying all of their property without even reasonable suspicion... they do it and get away with murdering people time-after-time because they can under a thinly-duplicitous cover of qualified immunity (at least in the US).

Although police at the borders don't have to have any reasonable suspicion for searches, racial profiling, secret watch lists and targeted intimidation are a likely consequent of an unfettered military-industrial complex that long since ceased to do more than security theater and carry water for the corporate elites. So it should come with zero surprise that such an empire's law enforcement acts with impunity however it pleases and only ensures to "serve and protect" the rich elites' and their property, effectively creating a socioeconomic apartheid of gated communities and post-apocalyptic anarchist favelas, both in terms of geography and public discrimination, that tears a society apart into a failed, third-world, backwards country.
