Unrelated to Fritz, related to company raids: Some time ago I worked for Kaufland (sister company of Lidl - Schwarz group, #3-#4 retailer company worldwide) and on all offices & hallways there were signs saying something like:

"In case of raids, cooperate with the police, do not throw away documents or break any device", which always seemed funny to me, as there was probably an incident that happened that lead to them putting this so often in the office.
