From Wonkblog:
Senators agree on the need for reform, but are split on the how. "As a Senate panel took its first look Thursday at a key surveillance reform bill on the one-year anniversary of Edward Snowden’s first disclosures, lawmakers agreed on only one thing: The measure needs work....Technology companies and privacy organizations worried about surveillance have warned — as some lawmakers did Thursday — that the measure doesn’t go far enough to actually prevent the bulk data collection it tries to ban. But several other lawmakers worried that putting phone companies in such a pivotal position for national security was a mistake." Alex Byers in Politico.
In other words, same old "duck and cover" because, well, "we've already got all that megadata... so... what's the harm in collecting more because... you never know..."
And/or:
"As a senator, I check my campaign contribution list regularly and, well, I wouldn't want that money to go away..."
And/or:
"Just trust us."
