Crass Circuit Televisual Violation

You're on CCTV! the notice brays,
In a brash, abrasive fashion.
They are so proud,
To boast out loud,
We're a mass surveillance nation.

Whence came this vulgar urge to spy,
To commit a crass intrusion?
How England has changed, 
Old values estranged,
We need a privacy transfusion.
