Also there is a distinct difference between refusing to enforce the law and exercising discretion. A quick lesson in law for you. There are very few occasions in the law which requires an arrest (family violence, violation of protective order, etc). Some departments go further than that and remove discretion on other items (DWI, Suspended License, etc). But other than those situations the officer has some discretion on what actions to take.

According to your reasoning if an officer fails to write a ticket or make an arrest on an offense than he is not keeping true to his oath of office. Then using that same line of reasoning, if a Dallas Police officer stops you or your family for speeding are you going to insist that he write you a ticket so that he is not violating his oath of office? Or would it be alright for him to give you a warning because you weren't going "too" fast.

[Ed Note: I'm not talking about discretion. Let's go back to the Hill incident. If an officer refuses to investigate or take a report regarding possible gang activity, don't you think this stretches that oath a bit?

I'd be interested in examples of situations where the Dallas Police might make an arrest, but where DISD Police would not--and the justification for the example.]
