First up, an armed citizen neutralizes perps in this video from Brazil.

Shoot until the threat is gone. He’s clearly trained for this.

Next video is from Washington State:

Instead, watch this off-duty cop from Baltimore try to save his barber’s life:

Unfortunately, the barber perished in this one. But at least the bad guy also received ultimate justice:

An off-duty Baltimore cop fatally shot a man who stormed inside a barbershop and opened fire, killing an employee, police said.

The gunman, identified as Carlos Ortega, entered The Bladi Style barbershop in Baltimore’s Medford section Saturday afternoon with a handgun and “fired it at one of the barbers” working there, killing him, Police Commissioner Michael Harrison told reporters Saturday.

An off-duty cop in plainclothes who was getting a haircut from another barber reacted immediately and “with great bravery produced his firearm” and fatally shot the attacker, Harrison said.

Cops identified Ortega, 38, early Monday as the man who killed barber Rafael Jeffers, 33, the Baltimore Sun reported.

Investigators believe Ortega was tied to two earlier Saturday shootings, including one that left one person dead. Another victim was listed in critical condition following gunfire near the city’s Greektown section.
