""No you silly man.
The person who discovers the fire may not know all that stuff and has a duty to tell as many as possible as quickly as possible.
Shouting fire is the correct immediate action.
It is certainly not an issue of free speech.""

You confirm the depth of your idiocy!

If you are ever in that situation and act as you suggest, you will have to live with the responsibility for those who are trampled and injured or killed in the stampede that inevitably follows as people run in all directions, not knowing where the fire is or where the safe exits are.

I can only hope that the victims' relatives sue the backside off you. I certainly would!
