Cop A does something potentially wrong.
Investigation of incident occurs.
Cop A is found to have done nothing wrong and is released without incident (continues job).
Getbiggers say, "There was a proper investigation and the cop was found innocent. Move on."
Same scenario, different outcome:
Cop B does something potentially wrong.
Investigation of incident occurs.
Cop B is found to have done something wrong and is found guilty and is suspended, fired, etc.
Getbiggers say, "The investigation was flawed. There is too much liberal bullshit. This police officer should not be in jail."
Conclusion:
It appears like getbiggers only like investigations when the cop is found innocent. Either you're going to respect the investigative process or you're not, despite the outcome. Can't have it both ways.
