Either you're trained in security procedures to know how to identify a threat, and how to prevent a threat from occurring, or you don't belong in any job that requires you to be highly observant, consistent, and thorough. I was taught that the only stupid question, was the one you didn't ask. I spent 25 years in uniform in NY State prisons. I had to be security conscious every day on the job, and it carried over to my personal life. It's not something you walk out of work each day and forget. If you do, then you're in the wrong job. I'm in my 21st year of retirement, and I'm still extremely security conscious, and I'm a 76, almost 77 year old woman. There was no excuse for what was allowed to occur last Saturday.
Nope, that doesn't work. There were LOTS of folks there that were "unfamiliar" with security and they easily spotted the perp on the roof with a gun.
That's just more meaningless chaff to pile on the cover-up.
Was there ever such a thing as a “temp” security guard brought in from some other police field?
