Case in point: the chart itself denotes a new policy re: firearm discharges and discharge review board.

I suspect it’s a mix of lower firearm availability and departmental policies restricting stuff like shooting at vehicles, warning shots, etc. Crime doesn’t appear to be the main story given chart’s muted 80s-90s increase relative to 70s peak.

The Danger Imperative was selected as a Finalist for the Hamilton Book Awards at UT Austin! Humbled to be selected alongside other finalists and the grand prize winner that explored vital topics cutting across free speech, politics, academic freedom, climate change, and more. Onward 🚀

When folks lie for fame & fortune- it hurts them & everyone who wants to believe in them &/or what they stand for. He was impressive & legit, but lied anyway- it's a character flaw, IMHO.

Tim Kennedy vs. the Truth
The popular manosphere influencer has built a career on his reputation as an MMA fighter and a Green Beret. But can we believe everything he says?

My latest in Texas Monthly: Tim Kennedy is a Green Beret, former UFC fighter, and manosphere influencer. He runs his own school in Cedar Park and, lately, has been spotted in the White House. But lawsuits and accusations of stolen valor threaten to bring it all crashing down. Gift link:

Excellent profile of Tim Kennedy by @michaelsierraa.bsky.social taking apart the various falsehoods he peddles. One of the mothers of his children on why he enlisted: “I do think it was a flare of patriotic nobility. But also, it was a very convenient stage left from two young mothers and babies.”

TASERs nor any other tech can end police brutality. Tech does not change the violent / coercive nature of policing. All tech can and will be misused and abused. I wrote about this a while back. Nothing has changed. www.cambridge.org/core/journal...

A lack of state standards leaves Mississippi police and sheriff’s departments on their own to decide when to use stun guns, and many give officers a free hand.

I’ve trained BJJ 5 yrs. But anyone who’s trained for a month knows that you don’t crank a rear naked choke for SIX MINUTES unless you’re trying to kill someone. After more than 20-30 seconds (very generously), you’re just choking an unconscious person to death. Full stop.

Any recs for the/a few key texts on the ascendance of the “influencer”? Maybe how “influencing” shapes more than pop culture / brands, but also HOW politics is done, how movements (R or L) form/function?
