This satisfies most of the requirements for bad legislation:
It doesn’t address the problem
It moves or expands the problem elsewhere
It restricts the freedoms of honest citizens
It criminalizes normal activity
It provides loopholes for the actual criminals
It creates, expands or further empowers bureaucracy
It gives congress the warm fuzzy feeeeeeeling that they are doing something
That's Amy Klobuchar's bread & butter.
Bingo -- you nailed it on nearly all counts!
As with most legislation, even the name -- The Smartphone Theft Prevention Act -- has little to do with reality. (Affordable Care Act, anybody?)
How is this going to prevent the theft of smartphones?
