In case you're (like me) wondering what "attempted lynching" means in the context of the article, consider yourself enlightened by the California Penal Code:
405a. The taking by means of a riot of any person from the lawful
custody of any peace officer is a lynching.
405b. Every person who participates in any lynching is punishable
by imprisonment in the state prison for two, three or four years.
I can't imagine this is what the law was written to be used for, given the usual connotation of lynching.
