>calling law enforcement when you find old work in the lab. MBA types.
It's not just MBA types. Needlessly escalating up the chain as a means to shirk responsibility is a broader societal trend. Post "what do I do" about anything anywhere short of a prepper forum and people will tell you to call some external authority, the police, your landlord, a credentialed professional, etc, etc, and wash your hands of the situation. Worse still, they will deride others for taking the responsibility of doing things themselves.
Odds are there's nothing of note in those vials. It's either a joke or the lab was previously doing something that's Nth order smallpox related so someone wrote smallpox on the vials because what's in them bears some logical relationship to something about smallpox, not because it's literally smallpox. And even if there is smallpox in there this is a facility that already works with similarly nasty things so they should already know how to deal with it.
Had the person cleaning the fridge brought this to their supervisor and they decided to dispose of it however the CDC will (there's published best practices for this stuff) people would be screeching about "why didn't you call the .gov to save you" as if the .gov would do anything other than follow the same best practices for disposal with the added extra step of collecting evidence to leave the door open to prosecuting people should they feel the can do so and stressing the crap out of everybody in the process.
Edit: Why don't any of the people that have decided my comment is wrongthink do me the courtesy of explaining why I'm so wrong?
