That is a difficult question to answer. I imagine there is always a balancing act. Especially if the police have some rule in place, it could create situations that criminals would attempt to take advantage of. However, I have always been of the mind that I'd rather a guilty person walk free than an innocent person not. And there are always consideration of how use of force can affect those who see it, with secondary effects creating, what I imagine, are the more troublesome effects.
