If you concede that they are willing to violate the Constitution with this NSA spying then why would they let this law not saying they can shut down phones for unjust reasons stop them?
From what I have seen in recent years I don't want to give this administration or any future one any new ways to shut us up and shut us down. We shouldn't assume that this is an effort based on good intentions to protect us from theft or terrorists.
Granted, a decade or so ago these concerns would have sounded far-fetched. But look at all that has happened...
1. The IRS, by a vastly disparate ratio, targeted groups seemingly opposed to the president.
2. There are new allegations of other federal agencies like the FBI, ATF, and OSHA harassing people associated with these groups.
3. Journalists like James Rosen were targeted.
4. Documentary film makers like Dinesh D'Souza are being targeted ostensibly on campaign finance related charges but he did make the movie "2016" which was highly critical of the administration.
There are probably other things that I have missed or that haven't yet come to light.
We can write these things off as anomalies or overblown or we can fight over them along party or ideological lines. But for how long are we going to ignore this pattern of government abuse and stop giving them more power and control?
I don't mean to sound really contentious because I think that we are not too far apart on this. I just think we should err on the side of caution with our liberties with today's US government.
