Why would the Officer ask him if there was a Gun in the Car?
Is that something new when you Illegally Park your Car now?
Is that a question a Meter Maid would ask while writing a Ticket?
If he fights it in court, he might have a chance of it being thrown out because the officer shouldnt ask without cause. But in DC court? Hope he has something like US Lawshield protection. That might help him out of it.
