For the first point outlined, you need to post the ENTIRE portion you are referencing. Also, the first point actually points to the second point you made in terms of the ONLY circumstances under which evidence of a crime may be retained. Additionally, the second point you linked to references sections of the USC that you really need to read to find your Constitutional protections.

Additionally, the disposition of what is described above isn't specified. For instance, if they get evidence of a crime about to be committed, law enforcement is legally allowed to use that information to stop the crime. If evidence of an unrelated crime is discovered during a legal gathering of evidence for a different crime, that evidence is admissible in trial. These issues have been addressed before by the Supreme Court.
Where did you get this information from? Was it from the leaked copy of the
warrant to Verizon showing this? I'm not sure where you get the idea that they're collecting the metadata without a warrant, because the evidence presented to support this claim WAS THE WARRANT.
So it's ok in your eyes for the UK to do it but not the US? Your personal vendetta is showing.
No. What I'm seeing in a person like you who will whine and complain all day about how your rights are somehow being violated, without actually being able to prove it, yet will turn around next time some attack happens and wonder why the government wasn't doing enough. Part of understanding the Constitution is understanding what the writers were trying to achieve when writing the text. The Fourth Amendment was designed to allow law-abiding citizens to be safe in their person and property against UNREASONABLE government searches. The point of the amendment was not to allow those who wish to do us harm to be shielded from the government as soon as they step foot in the country. The Constitution also gave the power to the Supreme Court to be the ultimate arbiter of what is Constitutional and what is not. That power was then propagated down to lower courts via Congress. All 3 branches of government have determined that the activities that go on are Constitutional. No American citizen has shown any loss of rights or harm suffered by the program. The only person here who seems to be running contradictory to the Constitution right now is you claiming all of this is illegal and unconstitutional based on your personal belief.
And no, I am not arguing the government can be intrusive as it wants. For instance, I'm not arguing that the government should be able to kick in anyone's door and randomly search for contraband. I'm not in favor of the government listening in on every domestic phone call (which someone has yet to prove.) However, I am arguing that if the government is monitoring terrorist Abu over in Pakistan and they find in their review of their material that you are calling him 3 times a day, then they should be able to monitor that communication, store it, and use to to prevent crimes.
Or maybe she is informed on how the program works and, like the Legislative, Executive, and Judiciary branches of our government along with the governments of other countries, see that it is actually not illegal and not spying on Americans. Maybe, just maybe, the leaders of these countries see the intelligence value of these programs and the good it does each of their respective countries and have decided that it is more valuable to keep these secret and use these to stop attacks rather than release all of the information to the public so they can feel safe that they're not being targeted and then do nothing else with the information. What have you done to look out for those to wish to do us harm today?
