The ABC News report shown below describes a man in the state of Washington who swiped 100 vials plus other items, while various videos described a man who took a vax vial from CVS and overnighted it to a lab for testing.

Is the sheriff department so clueless as to why these vials were stolen: "What would a thief want with 100 COVID-19 vaccines that you can get for free?"

The burglary happened last week at a dental office in Purdy, about 30 miles southwest of Seattle. The owner called 911 in the early morning on April 30 to report that someone had entered the building overnight and stolen 100 vials of Johnson & Johnson's single-dose COVID-19 vaccine, a vial of Botox and more than $100,000 in medical equipment, according to the Pierce County Sheriff's Department...

"So we ask the question, 'What would a thief want with 100 COVID-19 vaccines that you can get for free?' The answer is, 'We're not sure,' the sheriff's department wrote in a post on Facebook. "But we want you to be cautious if you come across someone who offers you a vaccine outside of official vaccination events, medical/dental offices or pharmacies."
