I&#x27;ve used a service called docusearch. I believe it&#x27;s a network of private investigators across the US. You have to select from a few &quot;permissible purposes&quot;. I&#x27;ve used it two or three times to pull plates of people dealing drugs on my street. I used the &quot;Motor Vehicle Safety&quot; category for these. I live right on a county line, so it helps me direct my calls to the appropriate police department, also, I like to know who these people are in case something worse ever happens.
