Illegal arming and misuse of firearms
HLINOVSKÝ, Jakub
This thesis is focusing on the issue of illegal arming and misuse of firearms. The exact number of illegal weapons and their incidence is virtually undetectable. Illegal armaments and with that closely related misuse of firearms are global problems, which are not necessarily connected with criminal activities. The objective of this thesis is to theoretically and empirically map the issues of illegal arming and misuse of firearms in the Czech Republic. In the introductory theoretical section are define fundamental concepts and summarize the Czech "weapon" legislation in force. The section also describes the preparation for the implementation of European norms and with that connected preparation of the Czech weapon legislation change. The section follows with a description of the types of weapons, methods of obtaining legal weapons and firearms license, incursion of weapons into the black market, illegal weapons, their legalization and use of legislation in the fight against illegal armaments. There are also specific cases connected to the misuse of firearms, which illustrates the topicality of the addressed topic. The data, of the practical part of the study, were obtained from the official statistics of the crime department and statistics from the Police Presidium of the Czech Republic. The objective of the study is to descriptively map and analyse development of emergencies with the use of firearms in the Czech Republic in the years 2010 - 2019. Three basic research questions are formulated, to which an answer will be sought. The questions will be answered using the mapping of the development of illegal arming and the misuse of firearms in the Czech Republic. Furthermore, the definition of the activities of individual components of the integrated rescue system in the intervention against an active shooter and legislative measures focusing on the issue of firearms in the civilian sector. In the period under review the results of the collected data show that the incidence of cases of illegal arming stagnates and the misuse of firearms has been declining for a long time. Legally held firearms are more often misused to commit crimes. It was also found that weapons are the most frequently misused for dangerous threats, intentional assault and robbery. The results of the research and the conclusions can be used for study purposes and as material for the protection of the population. It is important to address this issue, as the effects of illegal arming are significant. The long-standing unresolved issue of illegal weapons could cause many serious problems with an impact on human health, lives, the economy or possibly society as a whole.

Suggestions for changes in the production of a part "revolver trigger"
Jiráček, Jan ; Chladil, Josef (referee) ; Kalivoda, Milan (advisor)
The study deals with production technology of “revolver trigger“. Final assembly is short firearm ALFA Steel and its model series of ALFA-PROJ, Ltd company. Introduction submits an explanation of trigger technology suitability. The following analysis describes current manufacturing process, which has manufacturing inaccuracy problem. Furthermore rootcause of manufacturing inaccuracy was determined and analysis of suggestions for changes (including modifications of technological process) was realized. Based on experiment dimensions were measured on provided samples of suggest production in Technical Control Department. Dimensions of triggers manufactured by current production were verified during the experiment too. Results were compared according to the rejects of production. In the final phase of the study manufacturing labor costs were compared for the one piece of trigger with the new suggested technology.
