Hi Barrett,

This is just a quick note I'm sending to various people whom I know are currently researching companies involved in the supply/manufacture of surveillance technologies.

I'm going to be reporting weekly on surveillance tech & related issues for Slate's Future Tense section beginning next week. So if you have anything you think I should be covering at any point -- now or in the weeks/months ahead -- please do get in touch.

Also, feel free to put word out that I'm actively working in this area and seeking tips. For the security conscious, I can be reached through various encrypted methods here.

All the best,

Ryan Gallagher
