So why were a lot of police donating blood in Goulburn on Thursday?
It was all part of the Bleed4Blue campaign.
New Police Academy boss Superintendent Rod Smith said the campaign is a blood drive created for the policing community, as well as the general public, to give back following the stabbing of Detective Sergeant John Breda.
“It started with the tragic stabbing of one of our fellow officers at Maroubra,” Superintendent Smith said.
“That inspired the NSW Police, via our commissioner, and the Academy staff and students to come down and donate blood for the benefit of everyone when it is so desperately needed.”
Sergeant John Breda needed more than 44 bags of blood to save his life, after being injured in the line of duty.
The challenge is on for police across Australia to take part to determine which state or territory can donate the most blood during February.
In Australia, roughly nine million Australians are eligible to give blood, but only about 500,000 donate. With one in three Australians needing blood at some point, the NSW Blood Service is looking for an extra 2000 donors.
