This is interesting. Normally police departments claim they have few ways to catch corrupt police. And I think there is more than a little truth to that. However, in this case the article shows that corrupt police are revealing themselves through the practice of destroying equipment. This could be an indicator that acts as a "canary" for police corruption! If police departments appropriately monitored such indicators, they may be on verge of discovering an easy method to spot criminal police officers before they do the damage to society.
