Despite any claims to the contrary, LEOs tend to have all the usual human flaws and frailties. So if the regs say it has to be there, but don't say anything about obstructing the view...Some guy who got up on the wrong side of the bed
is going to say "Well, the name isn't on the transom" and "sign here please". Or at least, has the option to say that.
When I had my first driver's license
and was still on probationary status, I asked a traffic cop how to get someplace. He said "You see that sign that says No Left Turn? Go down to that sign and make a left."
Ahuh. OK, make a left at the no left turn sign.
You just can never tell who the good guys are, even if they're wearing white hats.
