very high levels of overcrowding and lack of basic minimum conditions such as food and drinking water; and viii) the alleged lack of effective judicial response to such events "; b) the possible beneficiaries of the provisional measures are fully identified by the State of Brazil in as much as they make up the prison population at the 'Professor Aníbal Bruno’ prison. According to the latest information provided by the petitioners, in February 2014, there were 6,644 persons incarcerated in the center. Similarly, the prison staff and visitors in that center are also clearly identifiable; c) as part of precautionary measures in this case, the Commission considered that the extreme violence within the 'Professor Aníbal Bruno' prison has reached a critical level that has killed and affected the integrity of an alarming number of people and has taken shape in many forms of violence that operate simultaneously. That is, as a result of the actions of State agents and the absence of effective measures to control violence amongst the prisoners themselves. There is also consistent evidence of inhumane detention conditions that constitute a factor that exacerbates violence in the center. Thus, the alleged beneficiaries are in a situation of extreme gravity and urgency and risk of irreparable damage that requires the immediate adoption of provisional measures given the ineffectiveness of the precautionary measures issued by the Commission; d) despite the adoption of precautionary measures, the State has not taken the necessary measures to protect the life and personal integrity of the prisoners at said institution. The State’s response has not responded to the immediacy and urgency that the critical situations and extreme violence so require. To the contrary, as noted, the Commission has received consistent information regarding hundreds of deaths and torture and cruel, inhumane and degrading treatment in the prison 'Professor Aníbal Bruno' to date, not only by prison staff but also by other inmates. The Commission stressed that the last registered murder of an inmate at said institution happened only a few weeks ago and was allegedly perpetrated by another inmate. The most recent facts reported by petitioners are not isolated events. From the monitoring of the precautionary measures of the Commission, it can be identified that these very recent events form part of a continuous and growing increase in violence. Thus the continuity of the risk factors already described by the Commission, allow for the inference of an existent imminent risk of death and additional harm to life and personal integrity; e) for the Commission, the vast majority of people killed and injured were done so through the use of knives and firearms, and thus it can be inferred that arms trafficking took place in the detention center by the prisoners, that the State backed the practice and use of the 'chaveiros,' as well as alleged examples of the indiscriminate use of force by prison authorities. Thus the Commission highlights the lack of effective control in the 'Professor Aníbal Bruno' prison by custodial authorities, which allows for the inference of an existent situation of extreme gravity and urgency and risk of irreparable harm, and f) the information provided also places prison staff in said prison at risk as well as the visitors. This is evidenced by the alleged facts reported by the 4
