"The Justice Department went to the FISA court and admitted giving misleading, incomplete and erroneous information on 75 wiretaps."
You seem obdurate to the fact that this "erroneous information" consists of leaving out that some of the people being tapped also were also of interest due to their criminal actions.
The Justice Department saw no need to mention that. It's all part of the Gorelick Wall that was strictly an artificial construct.
This is why they were called "trivial objections." 3,000 people may have died because of some pointless legalism. You defend that?
The government failed to mention it because they knew under existing law, they were not legally allowed to obtain the warrants under FISA if they told the court they were to be used for criminal prosecution vs foreign intelligence surveillance. Intelligence surveillance had to be the primary purpose, not building a criminal case. That was the law at the time under FISA. The Patriot Act changed the requirments. Now you can call that a trivial objection or an artificial construct but it was the law at the time. Neither the Clinton administration nor the Congress (even the Republican controlled congress) saw fit to change it.
