[Star Wars: A New Hope] Why were the crew of Leia's ship fighting back? Aren't they part of the same government and this is basically a traffic stop?

Leia's support of the Rebellion might be an open secret but it is still a secret and she is still a legitimate part of the government along with the Empire.  Isn't shooting back against the Empire pretty much confirming she is part of the Rebellion?  If they were so outgunned wouldn't a better tactic be to bargain for surrender to give Leia time to hide the plans?  Why do they shoot back and then when she is brought before Vader then suddenly pretend that she is on a diplomatic mission?

Everyone on the tantive IV was a rebel. They'd just left an active warzone flee darth vader's flagship. It wasn't a routine traffic stop for them. Leia tried bluffing her way with imperial senate authority but everyone knew the empire wasn't taking prisoners or buying the idea that she was on official business. Technically they could pretend they weren't rebels and were duped into helping but the empire and especially Vader don't take chances that you're the one innocent bystander on a ship filled with rebels that just travelled to and from a secret imperial base without authorization.
