I actually worked with Bo Dietl on several occasions (back when I was doing law in New York), and while he is a great private investigator, he is as dumb as a doornail when it comes to politics and, well, everything else.  From Think Progress:

Today on Fox News’s Your World with Neil Cavuto, private investigator Bo Dietl argued that Arabs and Muslims should be subjected to racial profiling because Islam is a “Johnny-come-lately” religion and Muslims “pray to someone who wants to kill you.”.

Transcript:

And Neil, the bottom line is, this is a Johnny-come-lately religion. Christians and Jews have been around for 1600 years, 1500 years before. When they’re having a religion talking about killing people, I think we should reevaluate people who pray to someone who wants to kill you.

For those just joining, Islam has been around for just as long as Christianity, and it’s the second-largest religion in the world.
