> 1. Intel. Nothing can protect you from an aviabomb except you knew it was coming and hid before bomber arrived.
We're talking about bullets and Kevlar vests. That's like saying a vaccines do not protect you from a bomb so vaccines are useless. It's like saying that locking the door is useless because there are thieves who know how to pick locks. Or that putting a seatbelt is useless because a plane can crash down on you. I don't think this is how the world works, nor do I think this is how a human thinks. It's a spectrum with tradeoffs.
Kevlar vests protect you from bullets. You are more protected than someone without a Kevlar vest. Wearing a mask protects you. you are more protected from bullets wearing a protective vest.
I really hope you are trolling. If not, I hope you are in charge of no people. If you are, I hope they have common sense and don't listen to you. If they can't, I hope you don't nobody suffers the consequences of your judgment and logic. I'm at the point I really hope I've been fooled by a chat bot.
All the best.
