&gt;  We are talking about cops keeping their guns while off duties<p>Seems like a cultural thing. Cops in Germany are allowed to carry their guns off-duty, and when in uniform they&#x27;re allowed to travel in any passenger train they want (2nd class only) for free. Guess this is because unlike the US Germany doesn&#x27;t have dedicated &quot;railway cops&quot; and enough regular cops use the trains that way to provide on-board security.
