In an article for PJ Media published Monday, Debra Heine provides a closer look at David Kenneth Smith, a "rabid anti-Trumper" who was arrested on November 2 in Orange County, California for making criminal threats against an instructor at Soka University and suggesting he might go on a "killing spree."

Smith's beef with the instructor traced back to 2008 when the instructor played a role in disciplinary action taken against Smith for smoking weed. On November 1, Smith began exchanging emails with staffer. Things got very disturbing very quickly. KTLA 5 reports:

Smith, 39, apparently became frustrated over the email exchange and he allegedly emailed the staff member a link to a YouTube video that showed him holding a semiautomatic pistol on his chest.

The YouTube channel included other recently recorded videos where he allegedly talked about wanting to engage in a “killing spree,” officials said.

The Joint Terrorism Task Force was notified and quickly determined that Smith's threats were credible. Authorities arrested Smith on November 2 on one count of making criminal threats, to which he pleaded not guilty on Monday. He's being held on $1 million bail. After they made the arrest, they found "nine loaded firearms registered to Smith."

"News of his arrest was treated as a local story with no national significance," notes Heine. "However, if this freak had been a right-wing activist, he'd have been a front-page story in every paper in the country."

Below are some of the disturbing videos that led to Smith's arrest. It's not hard to see why the terrorism unit reached its conclusion about the credibility of the threat he posed. First, here is Smith explaining his rationale for going on a "killing spree," instead of either going homeless or committing suicide, like he says his father did:

Here is Smith declaring that "Trump is trying to kill us":

Below are screenshots from two other unhinged videos he posted — "Stories from College" and "President Trump and the Green Berets" — in which Smith deliberately features some of his weapons:
