Another central figure in the plot was Stauffenberg's eldest brother, Berthold Schenk Graf von Stauffenberg. After his arrest in July 1944, Berthold while being interrogated by the Gestapo, claimed that: "He and his brother had basically approved of the racial principle of National Socialism, but considered it to be exaggerated and excessive." On 10 August 1944, Berthold was tried before Judge-President Roland Freisler in the special "People's Court" (). This court was established by Hitler for political offences. Berthold was one of eight conspirators executed by slow strangulation in Plötzensee Prison, Berlin, later that day. Before he was killed, Berthold was strangled and then revived multiple times. The entire execution and multiple resuscitations were filmed for Hitler to view at his leisure. More than 200 were condemned in show trials and executed. Hitler used the 20 July Plot as an excuse to destroy anyone he feared would oppose him. The traditional military salute was replaced with the Nazi salute. Eventually, over 20,000 Germans were killed or sent to concentration camps in the purge.
