Should Budweiser should be sued for all the incidents of drunk driving?

death....or the manufacturer of an alcoholic beverage consumed by a drunk driver.

Let's assign blame only to the responsible parties, please.

I might add.

then you should be legally responsible for ensuring that is indeed true. Metal detectors and security staff are a must.

Does this include elementary schools and colleges?

they should meet regulatory criteria as to not mislead the public. How many mass shooters have been stopped due to a "gun free zone" sign? None.

Gun free zones mislead the public, unless they have security measures in place to back up the claim that it is indeed a "gun free zone".

Metal detectors, security staff, and ordinance sniffing dogs are a good start. Otherwise they should call it a "we hope it's a gun free zone." Truth in advertising.

Airports once you are past the security gates. Some schools already have these measures in place as well.

And what security measures they must take?

You might have administrative procedures at the federal level that are somewhat relevant.

I'll wait to see it on Netflix before having to deal with metal detectors and sniffing dogs. What you describe sounds like a police state. No thank you.
