"I don't need to know how encryption works" - true - not in detail but some knowledge on how it fits in would help.
"Terrorists can use encryption to communicate securely" (para) - true
"Security forces need back doors into encryption" - wrong
It not the facts she has wrong, though some could be, it's the conclusion. Terrorists and other criminals use all sorts of tools to plan and commit their acts but do you ban all of them just because it could be used that way?
What I found more worrying is the gaol time for those viewing "terrorist material" on-line. Who defines what is "terrorist material"? Government could decree any sites working on disrupting their plans are "terrorist material".
