 The WSP also often performs other duties such as enforcing environmental laws.These police officers in Navy-like uniforms often have inland or maritime shipping experience and are trained at the German Water Police School ("Wasserschutzpolizeischule") in Hamburg.For practical reasons the WSP of one state may have jurisdiction in the territory of another state (for example, the Hamburg WSP is in charge of a section of the Elbe River that spans the states of Mecklenburg-Vorpommern, Lower Saxony, Schleswig-Holstein, and Hamburg.)
