Warrants? We ain't got no warrants! We don't need no warrants! I don't have to show you any stinking warrants!
It never fails to amaze that people will pay to install cameras in their bedrooms and bathrooms, and yet are horrified when the footage is abused. I mean if you have to have security / sexurity cameras there then face them to the doors and the windows and remove the microphones.
Equally, when some tawdry tech commits thousands of crimes then they either use their own email address, ip address or credit card. I assume not every miscreant is this daft and the exposed morons are the tip of the iceberg.
