According to the Public Defender, one of the main problems of the investigation in the case of the events of June 20-21 is that they can not identify the riot police officers.

"One of the main problems is that they can not identify the riot police officers. Unfortunately, their identification numbers are often impossible to identify, which is really a problem. It is important that the law enforcement officers could be identified during such operations in order to establish their responsibility. However, it is very difficult to identify them like in the case of previous dispersal of demonstrations", - said the Public Defender.
