The children’s bodies were mangled & blown apart. DNA was needed to identify them. "Perhaps, there is an opportunity to increase regulations on ammunition…” "The use of expanding rounds on the battlefield is a war crime."

"Salvador Ramos, the 18-year-old gunman in Uvalde, purchased 375 expanding rounds. In 2019, a 21-year-old gunman in El Paso, Texas, bought 1,000" expanding rounds for his Walmart rampage…"

"Right-leaning media is now again straining to find any solution to mass shootings — anything other than increasing regulations on guns. Perhaps, there is an opportunity to increase regulations on ammunition instead.

As the Center for American Progress previously suggested in 2019, after numerous mass shootings that year, the use of hollow points — as well as any other novel ammunition — could be controlled through background checks, seller licensing, age limits, and bulk-sale reporting.

It would be a tiny step toward addressing the mass killings, but it would be more than what was done after the previous 26 school shootings this year so far."

After Uvalde, there’s still no gun control on the horizon. We can start by regulating hyper-destructive expanding ammunition then.

"Research into gunshot wounds in the USA is hampered by lack of funding. Federal-funded research into firearm injury, epidemiology, violence, and prevention is minimal." 

"Pathophysiology

The degree of tissue disruption caused by a projectile is related to the cavitation theprojectile creates as it passes through tissue. A bullet with sufficient energy will have a cavitation effect in addition to the penetrating track injury. As the bullet passes through the tissue, initially crushing then lacerating, the space left forms a cavity; this is called the permanent cavity. Higher-velocity bullets create a pressure wave that forces the tissues away, creating not only a permanent cavity the size of the caliber of the bullet but a temporary cavity or secondary cavity, which is often many times larger than the bullet itself.^[19] The temporary cavity is the radial stretching of tissue around the bullet's wound track, which momentarily leaves an empty space caused by high pressures surrounding the projectile that accelerate material away from its path.^[18] The extent of cavitation, in turn, is related to the following characteristics of the projectile:

• Kinetic energy: KE = 1/2mv² (where m is mass and v is velocity). This helps to explain why wounds produced by projectiles of higher mass and/or higher velocity produce greater tissue disruption than projectiles of lower mass and velocity. The velocity of the bullet is a more important determinant of tissue injury. Although both mass and velocity contribute to the overall energy of the projectile, the energy is proportional to the mass while proportional to the square of its velocity. As a result, for constant velocity, if the mass is doubled, the energy is doubled; however, if the velocity of the bullet is doubled, the energy increases four times. The initial velocity of a bullet is largely dependent on the firearm. The US military commonly uses 5.56-mm bullets, which have a relatively low mass as compared with other bullets; however, the speed of these bullets is relatively fast. As a result, they produce a larger amount of kinetic energy, which is transmitted to the tissues of the target.^[19][20] The size of the temporary cavity is approximately proportional to the kinetic energy of the bullet and depends on the resistance of the tissue to stress.^[18] Muzzle energy, which is based on muzzle velocity, is often used for ease of comparison.
• Yaw: Handgun bullets will generally travel in a relatively straight line or make one turn if a bone is hit. Upon travel through deeper tissue, high-energy rounds may become unstable as they decelerate, and may tumble (pitch and yaw) as the energy of the projectile is absorbed, causing stretching and tearing of the surrounding tissue.^[19]
• Fragmentation: Most commonly, bullets do not fragment, and secondary damage from fragments of shattered bone is a more common complication than bullet fragments.^[19]"

"As parents waited in anguish for news about their children following the school massacre in Uvalde, Texas, they received a chilling request from police. Officers asked for DNA samples from parents to help establish the identities of the children who had been killed in the massacre, the second-deadliest school shooting in U.S. history.

The request pointed to the obvious, horrifying conclusion that many of the children who had been killed were so grievously injured that it was likely impossible to identify their bodies.

How we got here should be obvious: the AR-15 rifle."
