It’s just fear that people will realize that there are three highly reliable predictors for who will be a mass shooter:
The Venn diagram of the people who claim every shooter is trans and the people who fit the above criteria is a single circle.
More and more, it seems people have just two choices when venturing out of their home: Go where there are no other people, or go where the crowd is MASSIVE (dilution effect).
Las Vegas Harvest Music Festival has entered the chat…
I’m talkin’ MASSIVE crowd. How much did the Colosseum in Rome hold? 300,000 (definitely NOT including anyone in the arena)?
The Amphitheatrum Flaujanum Colosseum is about 23,370 m2. The arena is about 3,965 m2. So the seating area is 19,405 m2. So it can fit about 46,572 people sitting down, or perhaps 83,830 standing-room-only.
wiki: That scans. According to the Codex-Calendar of 354, the Colosseum could accommodate 87,000 people, although modern estimates put the figure at around 50,000.
For some reason, the 300,000 was stuck (unused for decades?) in my head. Maybe that included a couple a hundred thousand of gladiators, victims, entertainers packed together on the arena floor! 
Perhaps you are thinking of Circus Maximus which had a much larger capacity (although that too has been recalculated)?
Not a mass shooting, but another campus shooting
CNN has had breathless coverage of this all night. 6 dead including the shooter. The shooter had a PI license and CC permit. He drove from Las Vegas to NYC, casually walked into the building from the street brandishing an M4 or AR-15 rifle, killed 4 people on the ground floor, and another on the 33rd floor before killing himself.
If I was conspiracy theorists I would say:
BTW that was not joke or any like that. That is what I believe conspiracy theorists are going to say about what happened If they say anything.
They will no doubt join forces with the racists who will surely be having nuanced and intellectual discussions regarding him being an apparent POC.
Sigh.
Police said Tamura had a history of mental illness, and a rambling note found on his body suggested he had a grievance against the NFL over an unsubstantiated claim that he suffered from chronic traumatic encephalopathy. He had played football in high school in California nearly two decades ago.
“He seemed to have blamed the NFL,” the mayor said. “The NFL headquarters was located in the building, and he mistakenly went up the wrong elevator bank.”
The note claimed he had been suffering from CTE — the degenerative brain diseasethat has been linked to concussions and other repeated head trauma common in contact sports like football — and said his brain should be studied after he died, two people familiar with the matter told The Associated Press.
The Flying Burrito Brothers missed it by two. Chance or deliberate?
A friend/colleague of mine works in that building. Here is what he wrote this morning.
Good Morning and thanks for reaching out. Yes, fortunately I was upstate yesterday, working remote. Sigh … we got the emergency text (from XXX) at around 6:45 p.m. about the active shooter at the building. What followed were eleven or so emails from lawyers at the office, who were told to shelter in place - lock their doors and turn off the lights. They all remained in place until 10:00 p.m., when the police came by to escort folks out. I can’t imagine what was going through their minds, honestly.
The entire building is closed today due to the ongoing police investigation, and our Co-chairs have OK’d remote work for the week.
Glad that your friend is safe!
He wasn’t right, but he wasn’t exactly wrong either.
