And if the officers guilty of misconduct lose their job, it's a sign that there is a system to deal with them and that it works (at least for those cases).

For sake of comparison, Norway has about 5.23 million people compared to 325 in the US.

Scaled up, it'd be like having 1,116 officers lose their jobs due to misconduct between 2005 and 2012.

Visibility to the issue in the US was substantially different in that time period than now, but I think the population helps put an absolute number into perspective.
