80 285. The Court considers that an expert opinion must be supported by sufficient information or verifiable facts, based on methods and reliable principles and must be related to the facts of the case. As to the assessment of this expert’s opinion, the Court finds, in the first place, that such opinion is not supported with sufficient information on the physical and mental health condition of the alleged victims. The evidence tendered regarding the ailments that the alleged victims would have suffered from is not enough and it does not specify whether such persons received any kind of medical care. The relevant issue in here is that in the expert's opinion, on many occassions, no specific reference was made to the facts of the case that would have specifically affected the health of the alleged victims and even constant reference was made to facts that do not form part of this case. Although it is useful to determine certain health problems of the alleged victims, it is insufficient to establish a specific relation between such problems and the facts of the case at hand. 286. Notwithstanding the foregoing, it has been proven that the alleged victims were subjected to intimidation and hindrances, and in some cases, attacks, threats and harassments during the exercise of their profession (supra para. 141, 161 and 279). In several statements, these persons mentioned that their personal and professional lives have been affected in different ways. Many of them agreed on pointing out that they were afraid of working in the streets 277 and stated that it was necessary to use bullet-proof vest and anti-gas masks in the exercise of their profession278. Even, some of the alleged victims expressed their fear for attending public places and covering certain events279. Some of the 277 Cf.
