Police are sworn to protect, serve and defend. As citizens, we are supposed to rest easy knowing that our men and women in uniform are keeping crime and anarchy at bay and maintaining peace, order, and sanity. In most cases, however, the police are more hated by the citizenry than the crime. Why this so?
While most police do the honor to their badges and do what they have been entrusted to do, many bad elements still exist in the disciplined forces. Being an officer means that you basically have powers of force and use thereof to maintain order. This right is however blatantly exercised to the wrong extents and ends by some policemen who view themselves above the law. In the worst cases and the vast majority of countries, police are used as tools by those in power, not to keep order, but to suppress and hush.
The police are a law unto themselves and making them accountable to the citizenry is a risk the power would rather not take.
If police were fully held accountable for all their actions, we would have fewer cases of such occurrences. It is easy to discern, through proper investigation, the nature of a case and whether excessive force was warranted. In many of these instances, however, there appears to be a blatant abuse of power, and thus an equally strong authority should check on how the police do their work.
A proper essay should look at the problem that exists that make the police behave the way they should. Countries have constitutional documents that should be strictly adhered to, and the police operate within the brackets of these documents. At least, in theory, that is. The law should not be applied selectively because this is a recipe for dissent, and quite soon the citizenry will get frustrated and rebel. Extra judicial killings are quite common in some countries where individuals perceived as a danger disappear without a trace only to surface later dead.
