If one actually reads the poorly-worded article, it explains:
“Something must of hit the primer of one of the bullets,” Bentley said. “The bullet stayed in the purse, but its casing put a hole in the purse and caused a minor leg wound.”
Which is what anyone with a passing familiarity with ammunition long suspected. And is why we keep seeing ‘news’ stories with almost all rifles being AK-47s, and all pistols being Glocks.
And small collections being referred to as arsenals.
Not to mention a political agenda.
