Cleared?

The headline says Police cleared in six G20 incidents but this is certainly a funny way to define "cleared":

In the majority of the cases, the officers accused of police brutality exercised their right to refuse to be interviewed by the agency.
The SIU said that it was difficult to prove any criminal liability in the cases because many of the officers could not be identified, because they weren't wearing badge numbers and were wearing similar-looking clothing.
In one case, the agency concluded that a 27-year-old man who sustained an eye fracture during a scuffle was the victim of force used by a police officer. The same officer was believed to have arrested the man, but when the agency went to look up the police report, they found the badge number that was recorded to not exist.
