&gt; The police shouldn&#x27;t be able to detain someone for over an hour without probably cause and without arresting them.<p>Once I got stopped and they decided they were going to get a drug dog, and then a warrant, for my car.<p>&quot;Am I being detained?&quot;, I asked. &quot;No, you&#x27;re free to go.&quot; &quot;Wait, I can just get in my car and drive away?&quot; &quot;Oh no, we&#x27;re holding your car as evidence.&quot;  I was in the middle of nowhere.<p>I don&#x27;t know under what grounds they can do that (or if it was actually legal), but the grounds are presumably much less then actually detaining you. But it amounts to the same thing. I don&#x27;t know on what grounds they could prevent people from going back in their home even if they aren&#x27;t being detained (are you really going to leave and not observe whatever the cops are going to do to your home?).
