The police report from that drunken Palin family brawl last month is finally out, and Bristol is reportedly claiming a neighbor called her insulting names, then knocked her down and dragged her around a lawn.

According to the Smoking Gun, the party at a neighbor's house turned violent when Bristol confronted a woman who had insulted her sister, Willow. Reports TMZ:

Bristol told police the homeowner, Korey Klingenmeyer, shoved her to the ground, dragged her around, and started calling her a slut and a c**t.

Korey and several other witnesses at the party saw it differently ... telling cops Bristol punched him in the face — he says he let her hit him 5-6 times before grabbing her fist and pushing back ... sending her reeling to the ground.

That scrap then sparked the all-out brawl — witnesses say Track and 3-4 other people came running to defend Bristol ... and all hell broke loose ... with the Palins, including dad Todd, taking on all comers.

Willow says several people at the party we're chanting, "F**k the Palins!"

And where was the one-time almost-Vice-President in all of this? Reportedly waiting in a limo for her family to finish up inside. (She did, however, exit the vehicle to pull the "do you know who I am" card when cops arrived, witnesses say.)

According to TMZ, prosecutors declined to file charges against the participants, who they say were all intoxicated.
