Then what purpose does lying serve? Usually it serves to cover up something that someone knows they did wrong. I'm also fairly certain that dismantling your server, destroying evidence, and the fact that she waited a full two years before destroying said evidence(During an investigation), and use of multiple servers and devices shows pretty clear intent.
Not only that but they can also show that the actions were a result of gross negligence, and Comey clearly stated that Clinton was extremely careless. Both words happen to be synonyms of gross negligence, showing up as references when searching for the definitions of either word. Given that she clearly broke all of those laws I showed, and the evidence I just provided, all things she was stated to have done by the FBI, she either grossly negligent or doing said things intentionally. Either one can be proven from a reasonable perspective. It's entirely possible a prosecutor wouldn't take up the case, but what's clearly evident from what we can clearly observe is that she's guilty. Lack of indictment does not mean lack of guilt. We can all clearly see what her intentions were. She was hiding her communications because she didn't want them archived, turned over what she was okay with being seen, then tried to hide what she didn't want seen, and dismantled her server.
If you disagree, then please explain to me what her intentions were when keeping her emails from being archived, deleting the work-related emails she didn't turn over, lying about her actions, and using multiple devices while claiming she used one.
