Huh? Why would .gov have the ability to collect evidence and information after a illegal search or stop. How does .gov have any right to information for violating our rights as citizens. If that is fine why can't government use this more often to instigate more illegal stops and such as long as the overall 'good' of society is protected. That is crazy.
If you are ALREADY under arrest due to the outstanding warrant, you property is inventoried.
