Who will protect us from the police?

I refer to the article A story of corruption and police abuse.

It scares me to read of numerous incidents such as this, and this is not the first time I have heard of police abuse of power.

Not only have I heard about corrupt practices but also of physical abuse and in extreme cases death in custody. Problem is, where do we go?

How do we approach them and who is going to protect us? This is the police force under the powerful Internal Affairs Ministry, run by the prime minister himself.

How do we, the public, take on the abuse of power by them? Who is going to speak up for us? Will we be safe in trying to combat it?

We voted our government into power so why aren't they doing their job in protecting us? Why did we vote for them? Will they stand up for us?
