1. Coordination, initial agreements
The approval was received on May 4 from the Department of Regional Security of Moscow signed by A. Mayorov. The applicants of the rally: I. Bakirov, S. Davidis, E. Lukyanova, N. Mityushkin, S. Udaltsov. In negotiations with the mayor's office, a group of applicants proposed repeating the scheme of the previous rally (February 4) to Bolotnaya, when the square was entirely diverted by the protesters, and the passage to it was opened from the end with two flows - along the embankment and along the Bolotnaya Street ( website of the Ministry of Internal Affairs ).
On the website of the Main Directorate of the Ministry of Internal Affairs in Moscow, on May 5, a message was published on the approval and scheme . It is difficult to judge the exact route when approaching the swamp and the location of the entrance framework. However, it can be seen that the area is allocated for the rally (including the square) . The plan is published without agreement with the applicants.
Scheme from the site of the Ministry of Internal Affairs: 
In reality, the police cordon left only one pass - along the Bolotnaya embankment. For the rally , only part of the narrow strip of embankment was fenced off, and not the entire area, as was supposed by oral agreement and according to the scheme of the Ministry of Internal Affairs.
The scheme of the real location and displacements of the police and demonstrators. From the Blog of the GIPerbol LJ-Juzer: 
The situation when the procession approaches to the marsh (frame of video broadcasting Minaev Live): 
Before the start of the rally (13:00 - the beginning of the stage of the scene), his applicants could not establish contact with the responsible person in the Ministry of Internal Affairs and even find out his last name. This was the only case in recent years when representatives of the Ministry of Internal Affairs did not invite applicants to sign paper about responsibility before starting and did not discuss the details of its holding on the spot.

4. Investigations and criminal cases
Journalist Danila Lindel on May 29 published a large selection of facts of exceeding official authority by police officers. Ilya Ponomarev and 20 deputies submitted in these cases a request to the prosecutor's office. The case is refused.
The only criminal case on the fact of beatings was opened at the request of the Communist Party faction at the State Duma. The reason was the curious case of the "beating of a pregnant woman", who actually turned out to be a young man, as a result of which the case was closed. “The haste of the investigation and the violations of the criminal procedure law committed by him led to the fact that the object of criminal encroachment was incorrectly determined (a person who was caused by harm). The case was initiated by a non -existent event (since the policeman did not beat a woman), which excludes the production of the investigation ”(explanation of the Prosecutor General).
According to the events of May 6, the SK opened a criminal case under Art. 212 (mass riots) and 318 (application of violence in relation to a representative of the authorities). 18 participants in the events appear as accused, 13 are under arrest (in jail - 12) until March 6.
