No, it's head-in-the-clouds idiocy driven by a fundamentally misguided idea of what law enforcement bodies are there to achieve. You also don't believe it for a second.
Judging and policing are two different things. We should all be equal before the law, but we most certainly should not be equal before law enforcement bodies. Their job is to prevent and solve crime and that means looking where it is most likely to happen and at those people who are most likely to commit it. If law enforcement bodies behaved as you suggest, they would waste vast resources, crime rates would soar and their clear-up rates would plummet.
Seriously, though, why on earth am I arguing with someone who's already conceded his approach to crime prevention and policing makes no practical sense? Fückssake!
