Police Corruption and Their Involvement

There is no question that police should definitely participate in internal investigations and research about corruption.  There is no way to dodge the bullet of corruption.  It is inevitable that some cops will fall to the temptations and benefits that corruption has to offer but all aspects of law enforcement have an obligation to cease the spread of this evil. Police who have nothing to hide should have no problem with this and in doing so more dirty cops will be overturned, deterring future ones.  The police have a moral duty to keep crime from leaking into the very system dedicated to preventing it.
If participating in internal investigations and doing research on corruption helps to stop this, then police should definitely be involved in these tasks.  There is a lot of loyalty involved in law enforcement and I can understand why some officers may be hesitant to talk about cops that they may be close to.  These officers develop bonds and it's hard for most to look past that.  Yet if an officer is suspected or is actually involved in corruption then one should be able to cooperate with such agencies like Internal Affairs.  If an officer has betrayed its department and their job then everyone involved in law enforcement should do their best to serve justice, and if they lack to do this they are just as guilty.  Corruption is a major problem in today's law enforcement and I feel that it is crucial for every cop to participate in eliminating this.
