The guy that did this post doesn't provide any links to prove what he claims, so we can't say for sure it's true, but I have a feeling it is. Others in the thread will probably verify if it is or isn't.
He makes a good point though. This could be an entity that allows these things to happen, or is behind it somehow. I don't know, but it's too strange that the same company is linked to the Orlando, San Bernadino, Washington Naval Yard & Ft Hood shootings. I think I read they are also involved with bringing in the illegal immigrants. And they are involved in other government buildings and nuke plants too. Perfect!
