Exactly.
Back in the 80's when the little portable televisions came out, DC passed a law prohibiting TVs in the front seat in order to deter people from watching Soul Train and Grizzly Adams while driving. My buddy pulled over a guy a few years back who copped an attitude. Guess who had a brand new, full-sized still in the box television on his front seat? And guess whose mouth got him a ticket for violating the 'no-TV-in-the-front-seat' law?
Best to stay under the radar and keep your moth shut.
You need to amend that to: "DC, along with virtually every state, passed laws"
Seriously, as if Maryland and Virginia do not have the exact law and still on the books and still prosecuted.
