Alternate caption for this pic (the turnout gear already shows that he's a firefighter; that he's a rapid response officer is (just) extra information — leave that out?):
You trust me to break down your door in the middle of the night and get you out when you're in trouble.
Do you trust me with the weapons I need to protect myself at my house?
Possibly add:
Fire axes, fire hoses, defibrillators and guns are all tools. Their purpose is to save lives.
{Re-word this however you wish, of course}
