Abstract
The development of drones has been exceedingly rapid in the last few years. They can be used in many different areas of life, they are fit to solve a range of problems, in fact, in some fields they may open up new horizons. Besides their advantages, however, we must also see their downside. This article will focus on the development of these unmanned aerial vehicles and will elaborate on the regulations affecting the small-size devices, which are the most widespread. This section will be followed by the introduction of their potential use in law enforcement, with special focus on the protection of prisons. The paper will also discuss what hazards are involved in the illegal use of drones with regards to jails, and what response can be given to these new challenges.
