Don't bring a 'bomper' to a gun fight

We were heading to a friend's house for dinner last night when we spotted the following little drama heading towards us in the opposite direction. A heavy, grey 4x4 was tailgating a smaller sedan, lights a'flashing and horn a'honking. The driver being thus asked to move over (or faster) lowered his window and waved a shiny metal object in the air....a rather large looking handgun. The guy behind had the huevos to flash once more before applying his brake.
