Either we need to redefine what probable cause means and say that police are not subject to it, or we arrest officers right away just as we would with any other person accused of committing a crime. Either we write new laws or enforce existing ones; we cannot have it both ways.
Let me be clear: as I have said repeatedly, I do not believe that all police officers are bad, nor do I believe that most are bad. But there must be a transparent, impartial and fair system to judge those that engage in criminal or unethical acts.
It is up to us to change laws on the books like 'Stand Your Ground' laws and push elected officials to enact regulations that hold police officers to the same standards as the rest of society. This is why we vote.
Civilians are arrested every single day - including innocent ones - and they must wait until their day in court in order to argue their side of the story. Police officers must be subjected to the same rules.
Local prosecutors work alongside local police officers on a regular basis and are therefore conflicted when it comes to prosecuting those same officers. They are under extreme pressure from local police unions and from rank-and-file cops.
