In this summary of five recent cases, CNN Tech asks, "Can the Law Keep Up with Technology?". Yeah, I know…I'm harping on privacy again…what can I say? Good things come in threes…
My only other two comments are, 1) you're not supposed to start a sentence with the word 'can', and, 2) the answer to the question is 'no'. There. Solved.
The law will never be able to keep up with technology. The day the law keeps up with technology is the day Congress is replaced by Deep Blue.
In the meantime, CNN's summary is worth a look.
