I don't generally respond expeditiously to homework assignments on the internet, so you'll have to give me time on that one. The top of my head is plenty good enough for most of those, as they're all widely reported. All of those are or have been government policy in this administration and/or the previous one. The ACLU has rightly attempted to litigate many of them.
Rubber stamp? Of over 20,000 FISA warrants requested since 2001, only FIVE were denied. That's a rubber stamp. Those were for mostly for wiretaps, but I think it's a reasonable bet to believe that no more scrutiny is attendant on covert searches.
Torture? Our country has repeatedly tortured detainees since 2001. That's so widely reported as to be indisputable. Don't play that silly business about how since they use some of those techniques in SERE, they're not torture. The reason they're taught in SERE is BECAUSE they're torture techniques used by our enemies. SERE was consulted in the development of these techniques for use in GWOT. That's publicly available, so don't pull OPSEC on that. Using physical coercion to obtain information is torture.
The scariest part of all of this is that secrecy has been used as an excuse to conceal government malfeasance. There are likely even more abuses that most of us will never know about.
We are supposed to be the good guys. If we ever win this conflict, it would be a travesty against all those who've died fighting if it was all for the sake of protecting an American way of life that we gave away in the course of "saving" it.
