2. DECISIVENESS — “An indecisive man is unstable in all his ways.” James 1:8 (HCSB)

3. AGGRESSIVENESS — “Be angry and sin not.” Ephesians 4:26 (KJV)

4. SPEED — “With blinding speed and power he destroys the strong.” Amos 5:9 (NLT)

5. COOLNESS — “God gave us a spirit not of fear but of power and love and self-control.” 2 Timothy 1:7 (ESV)

6. RUTHLESSNESS — “Hate what is evil.” Romans 12:9 (NIV)

SemperVerus™ Brotherhood/Sisterhood Launches to Help People ‘Stay True’

Comprised of 5 Catalysts + 1 Tactical Agent:
Prepare, Aware, Be, Know, Do, +Self-Defense

SemperVerus™ (Latin for “Stay True”) is a new dynamic motivational communications operative that has as its mission to inform, inspire, persuade, impel, and invigorate men and women to personal life-changing positive commitment, decision-making, and responsible self-defense awareness. It accomplishes this objective through its website and Twitter stream (semperverus.com and @semper_verus), publications, reminder wristbands, the SemperVerus Brotherhood™ and SemperVerus Sisterhood™ pledge, and group presentations.

“The best antidote to a culture shifting to bad behavior is to re-normalize good behavior,” says social observer and author Seth Godin. SemperVerus (the “V” in Verus also stands for the Roman numeral 5) believes the best way for a person to avoid drifting off-course into bad behavior—deviating from his or her life’s “true north” of fulfillment, happiness, and civic well-being—is by attending to 5 transformative catalysts that culminate in 1 tactical agent:

I.    Prepare:  putting your life into proper condition and readiness to successfully handle material and spiritual foreseen and unforeseen circumstances.

II.   Aware:  heightening attentiveness to be alert to—and anticipate—dangerous potentialities and temptations, as well as edifying opportunities.

III.  Be:  developing rich personal leadership character of exemplary moral and ethical quality.

IV.  Know:  becoming a life-long learner to clearly, and with certainty, apprehend situations from which to benefit personally and others.

V.   Do:  resolving to intentionally and skillfully act to accomplish positive and fruitful outcomes.

+    The sum total of these 5 catalysts cultivates the strategic and tactical agent of Self-Defense: the intelligent ability to responsibly protect yourself from menacing spiritual and physical threats.

The SemperVerus website blog is a regularly updated source of developmental information and curated resources for personal leadership and self-defense, with articles focusing on the Prepare, Aware, Be, Know, Do, and Self-Defense categories, such as:

Important Judicial Decisions Regarding Self-Defense Law

The following legal decisions concern the law of self-defense. Some of the rulings are final and others are not. They’re presented here, along with salient excerpts, to be read for their excellent judicial logic about the absolute civil right of armed self-defense as established by the framers of the US Constitution.

District of Columbia Court of Appeals ruling: Tyree Benson v. United States (March 5, 2026) by Associate Judge Joshua Deahl (pdf).
This ruling states that, because firearm magazines capable of holding more than 10 rounds of ammunition are in common and ubiquitous use for lawful purposes, the District of Columbia’s outright ban on them violates the US Second Amendment, and that these magazines qualify as “arms” protected by the Constitution.

“Magazines capable of holding more than 10 rounds of ammunition are ubiquitous in our country, numbering in the hundreds of millions, accounting for about half of the magazines in the hands of our citizenry, and they come standard with the most popular firearms sold in America today. Because these magazines are arms in common and ubiquitous use by law-abiding citizens across this country, we agree with Benson and the United States that the District’s outright ban on them violates the Second Amendment.”

“An 11+ magazine facilitates armed self-defense because it is used to load a firearm, and it then feeds successive cartridges into the gun’s firing chamber as a person shoots—a particularly essential feature for semiautomatic guns—eliminating any need to manually reload the gun until the magazine is spent and itself needs to be reloaded….Because magazines feed ammunition into certain guns, and ammunition is necessary for such a gun to function as intended, magazines are ‘arms’ within the meaning of the Second Amendment….Magazines of all capacities are thus arms covered by the plain text of the Second Amendment….Any components integral to a firearm’s operation, like magazines, fit comfortably within the Second Amendment’s protection of arms.”

“…arms that are utterly ubiquitous in this country, like the hundreds of millions of 11+ magazines, cannot be banned. Just as handguns cannot be banned because they are the most preferred [type of] firearm in the nation, the 11+ magazines that tend to accompany them are the most preferred type of magazine and likewise cannot be banned.”

“…one perfectly coherent view is that law-abiding citizens everywhere should have access to the same arms that are legal, widely owned, and generally available throughout the rest of the country.” *

US Court of Appeals for the Ninth Circuit ruling: Baird v. Bonta (January 2, 2026) by US Circuit Judge Lawrence VanDyke (pdf).
This ruling strikes down California’s open carry ban, finding it inconsistent with the Second Amendment and the nation’s tradition.

“For most of American history, open carry has been the default manner of lawful carry for firearms. It remains the norm across the country—more than 30 states generally allow open carry to this day, including states with significant urban populations. Indeed, several of our Nation’s largest cities and states recently returned to unlicensed open carry by explicitly authorizing it. For example, Texas reauthorized open carry without a license in 2021. Kansas likewise transitioned back to allowing open carry without a permit in 2015. And other states that placed restrictions on open carry in recent decades have also removed those burdens.”

“California’s ban on open carry in counties with a population greater than 200,000 (roughly 95% of the state’s population) is inconsistent with the Second Amendment’s right to bear arms as applied to the states through the Fourteenth Amendment. Applying the standard set forth in Bruen, the historical record makes unmistakably plain that open carry is part of this Nation’s history and tradition. It was clearly protected at the time of the Founding and at the time of the adoption of the Fourteenth Amendment….There is no record of any law restricting open carry at the Founding, let alone a distinctly similar historical regulation.” *
