Here are the things about the Hillary E-mail scandal that should given everyone pause.
1) Basic technical understanding. Hillary keeps talking about the future and continuing to lead America into the 21st century but does not herself see that conducting business with sensitive materials from an outside e-mail domain is problem. Not only does she not understand this she hasn't got anyone around her to tell her or won't listen to them. yet we are supposed to accept that she makes informed intelligent decisions.
2) Hillary as per her history "no controlling legal authority" type pattern is being evasive rather than turning that server over to the government immediately like any of us little people would have done once congress started asking about it ( to save our own skin ) she redacted and turned over copies of the documents. Okay minimally compliant, in the mean time though the chain of custody has been ruined. So whatever does surface in terms of classified docs etc will be harder to prove. She is working to construct a legal defense of herself based on various technicalities.
2a) While we might forgive 2 as simply being prudent, if we accept her vast right wing conspiracy assertions she is basically making her case in the court of public opinion on technicality as well. "Oh those things were classified after the fact", well fine but they were still sensitive and the Secretary of state of all people should have been able to recognize that. Maybe no crime was committed but its still was comically bad judgement and given you want our vote for president why can't you answer for that?
3) How does her negligent handling of sensitive materials square with her harsh condemnations of Snowden and Manning's deliberate leaks? Given those events were taking place partially under her watch did that trigger any introspection about her only procedures around operation security? If not why not? Do the rules not apply to Hillary?
