Balko said the court's decision comes after years of criticism aimed at the field of forensic pattern matching. He argues many of the techniques made famous on shows like CSI have little scientific basis. Many, he said, are based on little more than the best guesses of examiners who are mainly just eyeballing evidence.

He explained the idea that matching a mass-produced bullet to the mass-produced gun it was fired from, to the exclusion of all other guns, may well be impossible. Or, at the very least, we don't have advanced enough techniques to pull it off with the level of certainty you'd want for evidence that could put somebody in jail for years or even decades. Indeed, Balko noted, most examiners cited as experts in court are unwilling to even submit to outside tests of their methods.

Plus, Contributing Writer Jake Fogleman and I talk about how far the injunctions against President Biden's pistol-brace ban extend. Jake also tells us about his latest rifle purchase, which is a bit of a throwback. And I give an update on how I'm liking the Phlster Enigma and appendix carry.

Special Guest: Radley Balko.

Balko has spent a career documenting questionable police tactics, and he provides some unique insight into the Amir Locke case. Minneapolis Police killed Locke during a no-knock raid in February because he reached for a gun during the confusion caused by his apartment door being kicked in without warning. Locke wasn't the subject of the warrant and had no record, but he ended up dead.

Now, the police officer who shot him has been cleared of any wrongdoing.

He is far from the only person who has had their life or freedom taken without recourse as the result of drawing a gun during a no-knock raid. Balko gives background on a vast collection of people who have found themselves in the same situation.

We also discuss the delicate balance between respecting police, attempting to make their jobs safer, and upholding Americans' civil liberties. Balko explains his view on how gun-rights proponents should react when those priorities come into conflict. And he shares real-world examples of it happening, including the use of dubious ballistic matching evidence against criminal defendants.

Plus, Contributing Writer Jake Fogleman and I discuss California Senator Diane Feinstein's (D.) solution to last week's deadly shootout in Sacramento. And we have another member segment too!
