Per Constitutional law, no individual of this country is ever compelled by any legitimate force, to essentially be a witness against their own self. This is the way that it should be, for the state should always have the burden to prove what it is that they are trying to prove, without coercing or forcing the accused to confess to or to make statements that are self- incriminating. Yet, despite this Constitutional law, the application of justice within this country has situation upon situation, in which those so accused are essentially being convicted not upon the evidence, or of forensics, thereof; but often find instead that their own words, coerced or not, are the main source of their ultimate conviction.
When that government of, for, and by the people, behaves in the manner in which their objective of justice, is to trick, deceive, or to play upon the emotions of a given person, that has been placed into the vulnerable position of having had their freedom wrested away from them, by virtue of their being arrested or stopped, and further of which these persons are thereupon susceptible to all sorts of enticements or promises, forceful or not, or truthful or not; in addition of which they are suffering from the intense stress of their present incapacitation, of which, that lack of counsel, that lack of rest, that lack of perspective, that lack of freedom, and that lack of a fair playing field, are all conductive to the breaking down of such an individual, then it should come as no real surprise, that incriminating statements, true or not, coached or not, come forth.
It is never justice, anytime that a justice system or the process thereof, decides that it has the right to circumvent the fairness of justice, by working the angles that they have in play in order to simply get to the resolution that the state so wants to have, irrespective of whether it is just or not, right or not, or fair or not. Far too often, the government rather than seeking, first and foremost, to uphold fair justice, in a given situation, are instead looking for that easy way to get a conviction and in their hastiness to do so, therefore prefer the deliberate absence of allowing the other party to have their fair say, thereby precluding that the justice as so enacted is actually on some basic level, a fair and equable process.
Those justice systems that have meaningful laws put into place so as to uphold Constitutional standards for all of the people, but in application, thereof, effectively ignore such, have by their actions, shown the upmost disrespect for their own Constitution. When the point of the exercise appears to be to get convictions at any cost, so long as such is done in a manner in which there doesn’t appear to be any blowback to that system -- that isn't justice. Further to the point, when those that should and ought to know better, behave in a manner that reflects that they surely do know better but refuse to abide by their own lawfully applicable rules and regulations, then those that are disobedient to that, which is highest law of the land, should thereby be fairly punished for it.
