I understand the principle of what you're advocating for, but the unfortunate reality is that miscarriages of justice are the norm and not the exception. I'd put forward another principle; it is better to let 1000 guilty parties go free than to condemn 1 innocent party (and "innocent" here should be taken to include people who are committing a "crime" that is normally tolerated, employed as an excuse to arrest someone - each of us commits dozens of these "crimes" regularly, without realizing it). When we reflexively invite law enforcement into other people's lives, when we do not and cannot understand the situation at hand, we are not likely to promote a societal good. We are far more likely to promote a societal ill; that of overpolicing.

I'd encourage people to think of law enforcement as an adversarial entity, constantly trying to do everyone in, who needs your invitation to act. It might be because they need to drive their performance metrics up, it might be because they're overzealous in the pursuit of what they view as justice, we can't really know and it doesn't matter. When you give them that invitation, they will make the absolute most of the opportunity. If you invite that monster into someone else's life - you had better be damn sure that they are a real threat to the community. You don't want to ruin (or perhaps end) someone's life over a miscommunication.
