I don't know if this bit of kit could help anyone who's thinking of doing a bit of whistle blowing..

It's called Tails 2.6 and purports to give anyone "privacy for anyone anywhere"

https://tails.boum.org/index.en.html

It can be loaded onto a USB for use where ever..

I've tried it once.... But right now I don't have any whistle blowing to do..

There's lots of youtube stuff about verifying and installing - it's important that is.

Advice - if you use it just be careful.. And obviously don't be a galah and go looking at bad stuff or go buying bad stuff..
