There are ways and means...
You get round that by doing lots of Hadoop Analysis on said Data, that forms a brand new database, having 'no links' to its former data, but having all the intelligence extracted from it.
In the same way its difficult to prove copyright if someone even makes small changes to the way something was originally formatted, just look at the Samsung Galaxy X v the iPhone X.
Or you store the data outside the UK on NSA servers, or you get NSA to carry out work on your behalf (and vice versa).
I'm sure Theresa May's 'Brexit means Brexit', won't concur that 'Illegal Bulk Data Slurp means Illegal Bulk Data Slurp' gets deleted. It's not in Zero-T's nature to invoke such a ruling.
