According to the New York Daily News (via TPM):
When he was arrested Tuesday in midtown, Enright had a personal diary filled with pages of "pretty strong anti-Muslim comments," a police source said.
The source said Enright's journal equated Muslims with "killers, ungrateful for the help they were being offered, filthy murderers without a conscience."
And check out the picture of himself he posted on Facebook.

Let's be honest, posing with a pump-action shotgun, rockin' it like you're playing Guitar Hero doesn't make you're crazy. But couple this photo after you've tried to throat slash a New York Cabbie???
