Methodological stuff mostly, as far as I know. For example, they generally do not include firearms use by the federal police (which includes the Federal Border Guard and the anti-terror unit GSG-9). Because the police is primarily a state-level power (as in the USA), with the federal government having only a limited role (in fact, the BKA as the German counterpart of the FBI probably has less power than the FBI), this should not affect totals too much.
