right to freedom of thought and expression through the analysis of its two dimensions: the individual and the social. In this respect, the Court has indicated that those who are protected under the Convention have not only the right and freedom to express their thoughts, but also the right and freedom to seek, receive, and disseminate information and ideas of all kinds.517 272. The Commission has held that this right can be infringed when human rights defenders are victims of aggression, threats, and harassment.518 This, because such occurrences can silence or intimidate those who exercise their right to express themselves critically or to lodge complaints of alleged human rights violations.519 273. In terms of the right to personal integrity, the State has the obligation to adopt the measures necessary to prevent physical and psychological assaults, threats, and harassment used in order to diminish the physical and mental capacity of human rights defenders.520 The Commission has stated that such elements not only compromise their right to physical integrity, but also their mental and moral integrity.521 This, insofar as such [proceedings] produce anguish, fear, and insecurity.522 2. Probative value of the facts described 274. Regarding the allegations of violence, threats, and harassment against CAJAR members, the Commission has identified three sets of facts, as evidenced in the section on findings of fact: (i) facts alleged for which there is some proof they occurred; (ii) facts alleged that were reported to domestic authorities; and (iii) facts alleged and described by the petitioners in their communications to the IACHR. 275. The IACHR notes that, by their very nature, the acts of violence, threats, and harassment alleged in this case are difficult to prove. Accordingly, the Commission believes it is necessary to examine all of the information in the case file together and not strive to determine the probative value of each occurrence separately. 276. The IACHR first believes there are similarities between the acts of violence, threats, and harassment targeting CAJAR members. Second, the Commission notes that there are also similarities between those acts and the specific context of CAJAR, as indicated earlier in this report. Third, the IACHR observes that CAJAR’s specific context can be framed within the general context of human rights defenders in Colombia, as established in the previous section. Added to this, many of the facts alleged were reported to judicial entities. As indicated earlier, such reports have not been duly investigated. 277. The foregoing relates the multiple facts alleged to one another and, moreover, examines them in light of the more general context the Commission has been monitoring since the 1990s, as well as concurrently, in the timeframe in which they took place according to the descriptions made in the section on finding of facts. Based thereon, and with the added fact of the State’s failure to adequately shed light on the facts, the Commission considers that it has been sufficiently proven that in recent decades, the members of CAJAR suffered a series of acts of violence, harassment, and threats that, by their nature were tied to the human rights defense work done by that organization, impairing the members’ personal integrity, freedom of expression, and freedom of association. 3.
