You don’t mess with Monaghan’s Pub in Gywnn Oak, near Baltimore, MD. On one fall day in 2017, two thugs decided it was wise to rob the liquor store affixed to Monaghan’s Pub. They picked a nice day, but they failed to do their reconnaissance.
Next door, in the pub, a group of police officers were celebrating a retirement ceremony with dozens of off-duty officers attending.
The men entered the take-out portion of the restaurant and held an employee up at gunpoint.
The person who had been behind the counter knew that there was a retirement party for a police officer happening, so they went into the other portion and alerted the officers to the fact that they had just been involved in an armed robbery
When the robbers left with the loot, they didn’t get far before the off-duty officers ran out and tackled them. Apparently the two thieves got beat up pretty badly and learned never to rob a store when police officers are present.
