>>Far as the argument, it's weak because none of the claims they made last time came true. If anything, the U.S. is spying on and locking up so many Americans they might need to cut back so they can stop putting dangerous people back on the street.

Most of the increase in prison occupancy is due to drug offenses and this has been dropping since 2008ish; not due to 'spying'

>>Prosecution is so one-sided in FBI's favor that plea bargain rate is 97%.

This is 97% of the 92% of cases that are not dismissed or dropped by the prosecution after charges are filed. So only about 89% of the cases brought by federal prosecutors are resolved by a plea bargain. This also covers cases that are not brought or investigated by the FBI at all. The vast majority of criminal cases brought by prosecutors are slam-dunks(after all, they wouldn't charge someone otherwise). You don't need to believe the FBI in any case. Most criminal cases around the world are resolved very quickly and with a high conviction rate for the prosecution.
