> This is why Prism was illegal

Yet it still existed, and was used for surveillance by 3 letter agencies. Why do you think this is any different?

No idea why the two of you are using past tense. PRISM is still very much alive and well.

All Encrochat evidence was illegal in at least three different ways. UK Law enforcement didn't care. They just lied.

No it wasn't.

The Dutch cracked and wiretapped it. It has been held not to be intercept evidence per RIPA so capable of being used in evidence.

Most went guilty because they caught red-handed in the most egregious criminality you've seen.

Encro was designed to enable and protect criminal communications. It had no redeeming public value.
