My guess is that officers of the NYPD are already familiar with two of them.And so are members of the FDNY.
Yup. And even before this, they were getting an education with the Mohammadans opening fire on buses full of Jewish students, etc. A friend in the NYPD had to leave our mutual friend’s funeral early because a Mohammadan bomb-making factory had been discovered in a part of Brooklyn not far from where we were. That was a couple of years before 9/11.
