If a shady individual approaches you and your a simple daily life civilian, not a badass, not a war torn soldier, just Mr. Starbucks mocha mocha frappa luka chika chino in the morning before their massage, they attempt to sell drugs to you and they have a gun, are you going to say "NO, now please stand still while I take a photo of you" and not expect to get shot? lol I mean really, they'd just got shot if they say their calling 911 or their phone would be taken and destroyed immediately.
But in reality, at no point during any 911 calls does the caller say "Hang on, do you have a way I can send you this dank picture of the criminal?" lol
Honestly, dealing illegal substances is terrifying enough as is with all these damn ambient sirens
