Just about every radio station is all over this story.
Interviews being broadcast
21 victims being treated right now for injuries, including cuts from leaping behind tables or out through broken windows for cover.
12 people dead, including a police officer who stopped writing a traffic ticket to go into the bar when a man alerted him.
     The officer was within a few years of retirement from the police force.
The shooter had a Glock 21, 0.45 calibur handgun with an extended magazine (illegal in California). It had been legally purchased, locally. 
He was a former Marine, who reportedly had "mental issues," but somehow not severe enough to be detained or confined ("5150"). 
Hundreds of college students were at the bar before midnight when the shooting occurred.
They scattered immediately, leaving the bar by every possible means, back doors, fire escapes, out windows after breaking them.
The shooter was standing near the front door so probably nobody went out through that door while the shooter was active.
The shooter was neutralized quickly. He was a local resident, 28 years old.
Local colleges have cancelled classes for the day:
     Moorpark College
     Cal Lutheran
     Pepperdine University

One station reported that there had been some people present at this bar who had also been present in Las Vegas last year at that shooting.
.
Some of the people present had in mind that a shooting could happen and had already been thinking about what to do in such an event.

One station reported that there had been some people present at this bar who had also been present in Las Vegas last year at that shooting.

Well, I want to find out who those were and make sure I'm never too close to them.  :)

Las Vegas is one of those events where everyone and his uncle was there.

Lord, have mercy. Unfortunately, you can't fix crazy, and anyone who needs violence and killing to fulfill their goals is a damn lunatic.

May they rest in peace. Children are not supposed to die before their parents.

As I've told several people, this is just the latest regularly-scheduled mass shooting. Maybe no one died at all.

"Yawn".

Ask yourself:
How many of these shooters were MK ultras?
How many of these shooters were on drugs?
Actors involved?
.
There are just too many shootings. There must be a connection. These cannot be merely coincidences!

data was missing from the map, except the locations.

Remember also that America is the third-biggest country in land and population. There are 320 million people in a giant landmass with more guns than people. Inevitably a portion of those guns will go into the wrong hands.

As I've told several people, this is just the latest regularly-scheduled mass shooting. Maybe no one died at all.

Whatever you do, do not contact Adam Housley and his wife, actress Tamera Mowry-Housley, and tell them that you as a Catholic don't think their niece, Alaina Housley, was killed Wednesday at Borderline Bar & Grill.

From what I have read, FAKE FLAG EVENTS or WAG the DOG events are real acts of terrorism.

Real people are killed, but crisis actors may be employed to create a powerful emotional scene. For example, a white girl is commonly seen at most of these mass shootings. She wears straight long dark brown hair and is usually seen hugging other people and crying with them.

A common feature of these mass shootings is that they are used by the Deep State-controlled Main-Stream Media especially CNN, MSMBC, ABC, CBS, NBC, NY Times, LA Times, Politico, etc. to create a strong emotional appeal for GUN CONTROL.

And if everyone in the bar had been carrying a gun this would never have happened.
.
Sean Adler, one of the first to die, was a bouncer but he did not have a gun. If bouncers were armed they'd be able to do their jobs better.
.
Sean Adler, 48, worked at the Borderline Bar & Grill as a bouncer. He also owned a coffee shop called Rivalry Roasters, which he opened over the summer.
.
He was a soccer and taekwondo coach.
.
The Los Angeles Times reported that before Adler changed his career path due to a heart attack, he had planned to join the Los Angeles County Sheriff's Department.

i don't know about anyone else but I suspect it's generally true of many people. There are so many shootings that are questionable re: whether it was staged, fαℓѕє fℓαg,crisis actors, people died, people didn't- that emotionally I am kind of distanced from the "tragedies", if there actually are some.. I'm afraid to buy into any of it.  It's hard to intellectually invest in a macabre masquerade designed to confiscate guns, but most important, to confiscate US personally, if we do not have guns. If people died at any of these shootings, I am truly sorry, but the obviously contrived nature of most of these events cast doubts on the potential "real" ones.
I suspect , like others have said, that there are some composite "events", where it's planned but people actually died, and there is much infiltration of crisis actors and complicit government authorities and police.
I don't have TV,( so I may miss a lot of this) but I never see family, except one or two token spokespeople; never see a funeral or even a procession of funeral cars. All pictures of victims seem to be recent ( no history?) and even the pictures at the shooting site seem to all look  alike- staged. I wonder where all the ambulances and helicopters are- there should be scores of them at a major shooting- there is usually one or two placed perfectly and a bunch of people at the event carrying a "victim" or two. Many pictures show the people hugging and crying- no tears. Same every time. Where are all of the lawsuits? I'm sure many family of victims would lawyer-up and sue everything and everyone they can, but we don't hear about this. At 9/11 there were thousands of lawsuits, and the families were offered a blanket payment of over a million dollars that was attached to a gag order- most took it. I guess that was an expensive mistake for the globalist  perps.
Why didn't the Sandy Hook victim families sue the school, the police dept or the township? No, they only sued the federal government over gun laws, and proceeded to tour the country for gun regulation.
I know I sound jaded, but none of this sits right -psychologically it's all off-kilter and maybe it's part of the globalist plan to desensitize us to horror as well, I don't know. All I do know is these mass shooting are here today and gone tomorrow- look at Las Vegas (where I do believe there were mass casualties)
