Still in the Market

You draw the Walther smoothly from your holster and put one very well-placed shot right between the large man's eyes.  People shriek in fear as he falls like a tree struck by lightning.  The crowd mostly scatters, but one grim fellow approaches and says "My name is Ishmael Montoya.  You killed my brother.  Prepare to die!"

You have:

• Stylish fedora
• Bullwhip
• Vintage Walther P-38 w/ 7 rounds
• Well-worn leather jacket

MY RIGHT NOSTRIL IS PLUGGED. IF I HAD 2 LEFT NOSTRILS I'D BE AWESOME

Do you

• Shrug your shoulders innocently then shoot Ishmael in the face? -or-
• Beat a hasty retreat out into the desert wilderness?
