<sarcasm>Google would never collect personal data without permission!</sarcasm>
>> limited data had been "mistakenly collected"
I'm pretty sure we all know this isn't "true".
In all seriousness, this is a very serious topic. In the end, Google Streetview was withdrawn in Germany because what they were doing was illegal. I'm very surprised we haven't heard anything more about this.
I'm happy the UK has reopened the investigation because what the Mountain View corporation did in the UK, and to be frank is still doing, is also certainly against British law. Most individuals go to prison for a very long time for fraud/theft.
What idiot programmer writes a program to mistakenly collect data? I've been programming stuff since I was a toddler and to have "mistakenly collect data" is a fib.
