Bystander saves the day when a man tries to shoot up a methadone clinic.

He went through that hide-flight-fight progression pretty fast it seems. Looks like it was fight or die. I didn't know what a "methadone clinic" even was. I had to look it up. In case you don't know, here you go:

A methadone clinic is a medical facility where medications for opioid use disorder (MOUD) are dispensed-—historically and most commonly methadone, although buprenorphine is also increasingly prescribed.

Medically assisted drug therapy treatment is indicated in patients who are opioid-dependent or have a history of opioid dependence. Methadone is a schedule II (USA) opioid analgesic, that is also prescribed for pain management. It is a long-acting opioid that can delay the opioid withdrawal symptoms that patients experience from taking short-acting opioids, like heroin, and allow time for withdrawal management.

In the United States, by law, patients must receive methadone under the supervision of a physician, and dispensed through the Opioid Treatment Program (OTP) certified by the Substance Abuse and Mental Health Services Administration and registered with the Drug Enforcement Administration.
