Civil authorities constantly impress upon the population that they should obey the law, in which, most citizens believe that such a policy is very sensible, as their perception is that if the general population does not obey the law, than chaos and anarchy will quickly reign. While this sort of mindset has its place, this obedience to law, counts on two very important and fundamental factors, of which, one is basically that laws should be clear, reasoned well, and applicable to all; the other is that those that are working on behalf of civil authorities in the capacity of implementing the law, whether they are the enforcing arm of the police, or the prosecutorial arm of justice, should also be subject to the very same laws, and not above it, or alternatively having the ability to sidestep it at their convenience.
For instance, prosecutorial agents have an obligation not to seek convictions at all costs and at all times, but actually to ascertain the truth, which means that information that may not be beneficial to the prosecution but is germane to the case, cannot and should not be oppressed, in addition to the fact, that it should always be the mission of the justice department to utilize the weight of the justice system in a manner that is equitable and fair to all, as opposed to utilizing state resources to pressure those that are least able to defend themselves, such as the poor and indigent.
While it is one thing to do things in a manner in which the 4th Amendment which secures the right of the people to be secure in their persons and possessions unless there is probable cause takes precedent, it is an entirely different thing to constantly have workarounds which clearly violate the spirit, if not in actuality, the 4th Amendment, because the state has determined for whatever reason, valid or not, that certain people must be prosecuted, at all costs. In addition, there are the stealth resources which are utilized again and again such as surreptitious surveillance as well as going "undercover" in order to build up a case against criminal elements, or undesirables. So too, it's rather hypocritical when undercover police agents engage in illegal activities so as to not blow their cover, basically signifying that some people for the greater good or whatever, are allowed to participate in criminal enterprises as long as they have been sanctioned to do so by the state.
In actuality, law enforcers of all stripes, and of all areas, have by virtue of the fact that they are exemplars of the law to the public that they serve, must, be held accountable for their actions, and those given such privileges by the public, most definitely, should know right from wrong, and thereby show clearly know and apply the law fairly and equitably at all times. If, on the other hand, law enforcers are given wide berths and are not held accountable for their actions, we have set up, in effect, two worlds of justice, one in which the public is subject to the law and its attendant consequences, and the other in which privilege members of the law enforcement arena and their cohorts, are not.
