Hey, can I take a guess here?

3 farm boys of swedish descent, wearing ski masks (it is Minneapolis after all, and its cold) were trying to make their way to the lutefisk stand, when they were caught up in the protest.

Trying to get out of the maelstrom, they walked away, only to be pursued by ne-er-do-wells.

They drew their single action 22's they used for rabbits, and defended themselves.
