Even if black and hispanic men are more likely to commit crimes, I think this sort of policy/practice is problematic, and goes against my value system (and I think many people's). I believe that how you treat someone can influence their behaviors--and treating someone like a criminal can be more likely to influence them to create crime, by diminishing their trust in police officers, government, or society in general, and by creating a self-fulfilling prophesy. America is founded on the idea of innocent before proven guilty and requiring certain evidence (and warrants) before searching and detaining people. I think this is one of the reasons why. So I think, even if this policy is motivated by intentions of preventing crime, I think it's unacceptable and I think it may actually be increasing crime, not to mention perpetuating institutional racism.
