10. Also in Car Hacks, how and when did you contact Staten Island mechanic Steve Ferrello about car hacking? What is the name of his business or the business where he works? Where does he live? Do you have his contact information?

Ferrello has worked on several of my friends cars. I called to check and see if he was okay with me passing contact info along to you and was told by his wife that they had separated and he was living elsewhere. She said she'd give him a message, but didn't want to pass along his contact info without his ok.  I left your office phone number with her, as well as a brief explanation. Please let me know if you don't hear from him over the next few days.

11. In same story, "Hobbit" says he doesn't want to talk to us, so we've been unable to verify quotes and content with him. Can you help us here?

If you can point me to ways I can help I'd be happy to do so. Did he say why he didn't want to speak with you? Several of my sources have told me they have been contacted by numerous reporters and bloggers questioning them about whether they'd actually spoken with me and I think people are just tired of the barrage of questions that may be why Hobbit doesn't want to speak with you.

Or he may just not want to be involved in this whole mess. I'm sorry you're getting flack that shouldn't rightfully be directed at you. How would you suggest we proceed? As noted above, I didn't keep emails from sources used in this piece.

12. In the The Invisible Fighter, can you explain the circumstances in which you spoke to Col. Rowan and Michael Logue about the military developing camouflage technology for urban environments?

During a 'geek road trip' down the Mississippi river for wired news last fall, we spent the day at the Corps' Vicksburg headquarters. (Oct. 21). We primarily discussed tele-engineering and the corps efforts to control the Mississippi. But we also had a very brief discussion of emerging military technology, including the urban camo tech. I told Michael Logue when I left that I had enough material for three or four stories.
