Its almost like people voted their party without understanding exactly what they were voting for.
There is that, of course, but I'm actually more baffled by the fact that your country has police chiefs with a viewpoint of "people should obey the law unless I suddenly feel uneasy about the law"
That's actually a good thing: Being able to look at the law and assess it's value yourself.
Jaywalking is illegal but police rarely(if ever) arrest people for doing it. It's illegal but the crime itself is so minor that putting the full force of the law against it is unnecessary. Likewise, some laws are/were morally wrong and people break it (and police look the other way) because they know it's wrong or the law shouldn't be applied in the specific situation.
You also have application of the law. Sometimes letting a criminal slide for minor things yields you a safer area than if you tried to arrest everyone who broke any and every law. Or perhaps the punishment for a law is unfairly severe so as a law officer, you decide to let them go simply because they'd be punished in a way you feel isn't fair.
Granted, this is 100% subjective and relies on more variables than anyone can understand. But an officer that can think and make their own decisions is better than one who just follows the letter of the law no matter what.
Though I agree with Rama that he should be fired. Mostly for being naive.
