"First responders"
Dammit, they're "Second responders". After all, who supplies "FIRST aid"? Does your "First Aid Kit" sit next to your bleeding friend until the ambulance arrives? No!
Your first aid kit is used by the first responder -- the person at the scene, AKA you, until the second responders arrive.
You as first responder use your fire extinguisher until the second responders arrive.
And you as first responder use your gun until the second responders arrive.
Referring to the police, fire and medics as "First responders" only plays into the narrative of 'You don't need guns, that's what the "first responder's" job is!'.
OK, been meaning to get that off my chest for some time, and hearing it [mis]used on the news last night several times finally fired me up.
