This is where we disagree. For you being a cop is a job, for me it's a vocation and sacrifice.
I guess there are cops for whom it is nothing but a job, and those who see the profession as a vocation with sacrifice. And there are some for whom it has all three aspects.
You seem to think because they have a tough job, they can be allowed to commit crimes without sactions. Assuming the reported facts are all the facts, you do realize at least the one officer commited crimes, don't you? And there is the propriety of it as well. Why would you sit a woman in an interrogation room for several hours, alone with the previously arrested suspect? Why would you steal the SIM card? If there was no legal reason to confiscate the SIM card (normally the whole phone should be confisctated, and I bet that officer will the next time, or find a way to erase the memory), and she wasn't given a receipt for it, that is theft. Do you condone theft by police officers?
I do not. Mind you, police are human. Still, they must know the rules and law, and abide by them. For very minor infractions, the officers peers can have a positive influence if they point out the mistake. A chewing out by the shift sergeant or lieutenant might suffice. More and perhaps some days on the street are needed. Worse or repeated infractions might require termination. Callous disregard for the law might require charges being filed and going to court. Somewhere along that path, if the department is big enough, an office might be referred for psychiatric counseling.
But these constant reminders are sometimes needed because in fact police are human and prone to mistakes or reacting in anger. If there are no sanctions for mistakes, why would they change. Over time, a police officer who gets a reputation of treating suspects and arrestees with respect, and not using more force than necessary, will gain respect. That may bring them information they wouldn't get otherwise, or even get them assistance in bad sutuations. It doesn't happen overnight, but it does happen.
So, no, I don't buy that police get a free ride. For relatively minor infractions, I don't expect the public to know everything that is done to an officer either. But no totally free rides.
