Late last week, police arrested a man for allegedly sending threatening messages to Colorado state Rep. Rhonda Fields (D), a supporter of gun safety laws featured in a recent ThinkProgress video. Fields sponsored bills banning high-capacity magazines in Colorado and requiring universal background checks for gun sales and transfers.

According to police, a man named Franklin Sain sent six emails, one voicemail and one written letter to Fields that were riddled with obscenities, racial slurs, sexist language and violent threats:

“I guarantee there is not enough law enforcement or military to stop an all-out overthrow of this government if you or that n—– president tries to take our guns,” one e-mail dated Feb. 13 reads. “Guarantee we will make World War I and II look like child’s play, many will die. Be prepared.”

Another e-mail expresses hope that someone would “Giffords” both Fields and Rep. Beth McCann, a reference to the 2011 mass shooting that nearly killed Arizona Rep. Gabby Giffords.

The paper letter attributed to Sain states, “There will be blood! I’m coming for you, n—– b—–.” . . . “Limiting magazine sizes is stupid and will not work,” he wrote on Feb. 13. “I for one have 100+ 30 round mags and 150 round drums. I will never give those up and I am far from being some whack job.”

In an email to Fields the following day, Sain wrote: “I ordered a ton of new 30 round magazines today C***bag—go f*** yourself and your new law—we won’t abide by it—C*** N*****.”

Before she joined the legislature, Fields’ own son was shot and killed as he waited to testify against a gang member.
