When someone successfully becomes a police officer, it is assumed they are a law abiding citizen with a high moral standard. When someone is working on their own agenda, it is often hard to tell them apart from the rest of the group. That being said, it is still very difficult for someone to make it through the system as a corrupt police officer. In some cases a good person can begin to head down a bad path. If that is the case, it would be near impossible to weed out before something major happens.
Bad cops are bad. Period. They do not help people and only help themselves. The average citizen cannot trust cops if municipalities do not work hard to end the epidemic of corruption that is ravageing our police departments and sheriffs departments. We need to do a better job of never allowing these people to become officers in the first place.
How can the people have any faith in their police forces? The police are human and make mistakes too but what we are seeing is rampant lawlessness. Those that are there to serve and protect are more and more holding themselves above the law. There will always be those that seek to do harm but when we are fearful of the police and their activities, whether known or not, who can we turn to?
No, it doesn't seem that municipalities do enough to weed out bad cops. It's becoming common to turn on the news and find a story about another officer acting inappropriately. Law enforcement is a difficult job and we need to respect and support our good officers, but more has to be done to weed out the bad.
