Since the inauguration event in 2000 GPEC^® has developed to be Europe’s biggest closed specialized trade fair for Police and security authorities. The event is regularly held under the patronage of the Federal Minister of the Interior. GPEC^® comprises all subject and equipment areas of law enforcement, public and homeland security, serves as One Stop Shop with regards to save resources with authorities and is in constant exchange about current requirements. A framework programme including conferences, official working group meetings and practical trainings makes GPEC^® again and again to be an indispensable branch forum. Also in its 12^th edition as specialized trade fair exclusively for members of authorities GPEC^® provided again the confidential framework for the exchange with top leadership personnel, procurers, technicians and end users on Federal and Länder level, from Germany and all over the world.
