> A US Senator from Texas literally said yesterday that we should station "good guys with guns" (armed security guards) to prevent school shootings.

Yeah, except there was a police officer right outside the building already:

> The suspect was immediately engaged outside the building as he approached the school by a Uvalde Independent School District police officer, who was shot by the suspect, the sources said.

And this isn't the first time on-site individuals have been useless:

Even if officers respond with-in a minute, you still have multiple deaths and many injuries:

> Police at the scene engaged him within a minute of the first shots being fired, firing 18 rounds and hitting the gunman several times.[5]

The solution is always to spend more money. It reminds me of eating and then going to the gym to lose weight, rather than just not eating as much to start with. But eating less makes fewer people rich, so we see fewer ads promoting it, less PR and so on.

In fact it was one such person who ended the killing spree in question.

Also "the only thing that stops a bad guy with a gun is a good guy with a gun" has been an NRA talking point for years.
