Grötsch was elected to the first Federal Police Commissioner in 2023.
The Federal Police Commissioner has the task of identifying and investigating structural deficiencies and undesirable developments in the Federal Police, the Federal Criminal Police Office and the police at the German Bundestag (federal police authorities). It also investigates misconduct by employees of the federal police authorities, in particular that which results in a violation of fundamental rights, in particular Article 3 of the Basic Law (prohibition of discrimination).The commissioner has a team of 18 employees working on his staff.[10]
Grötsch sees the compatibility of membership in the right-wing extremist AfD and serving as a police officer as problematic. The vigilance of emergency services against right-wing extremism must be heightened, he said in March 2024.[11]
