Patriot act, NDAA, warrantless wiretaps, xray scanners, TSA in general (i've not experienced it, but I know people that have, that have been pulled off and stripped searched for no apparent reason), police pulling people over and demanding to see their phone (worked with a guy that they did that too, they thought he was waiting for a dealer but in reality he was waiting for his wife to drop off his son, then they tried to ticket him for being on a cell phone while driving, even though he was parked), the list goes on.
Some of this stuff has happened before with cops. Nothing new. We have new government agencies vying for relevance.
The biggest changes after 9/11 was access to gates, and the image scanner. Other then that the TSA crap is pretty trivial. If you really look at, most of it is to make people feel safe.
The NDAA is big, but its not relevant in the USA only outside.
What provisions of the partriot act have stripped us of freedoms we use to have?
How are those invading our privacy?
