The deportation proceedings against John Kalymon, a Ukrainian police guard in L'viv, which have been in progress for several years, produced a legal judgement that can be read here. The crucial finding is that there are documents in which Kalymon accounted for his use of ammunition by stating that he shot Jews. I quote these below to indicate the brutality of the police's regular activities, from which readers can deduce their own conclusions:
A report dated August 14, 1942, indicated that “Iv Kalymun recorded that he fired four shots while on duty,” wounding one Jew and killing another. Further, the chief of the commissariat filed a summary report on the same date indicating that policemen “delivered 2,128 Jews to a central assembly point.” The report stated that twelve Jews were “killed while escaping,” seven Jews were wounded, and that “Ivan Kalymun” expended four rounds of ammunition. Additionally, on August 20, 1942, “Kalymun” fired two rounds of ammunition used during operations where 525 Jews were delivered to an assembly point; fourteen Jews were shot and killed and six were wounded. The following day, “Ivan Kalymun” shot two rounds of ammunition in an operation where policemen rounded up and delivered an additional 805 Jews. In June 1943, Kalymon’s commissariat participated “in the liquidation of the Jewish ghetto” where Jews were shot or sent to forced labor camps. From November 19 through 23, 1943, all UAP members in L’viv, including those in Kalymon’s commissariat, participated in massive search operations to locate and to turn over any remaining Jews in the ghetto to German authorities.
