“There really wasn’t a prosecutable case”
James Comey is adamant on the legal view of Clinton’s emails:
The case itself was not a cliff-hanger; despite all the chest-beating by people no longer in government, there really wasn’t a prosecutable case.
I suspect part of that is the details don’t hold up, and part the lack of any wrong intent. Many of us now deal with hundreds of emails a day, and sympathize with the number and variety that a high-ranked government official must handle. Most either go unread or are cursorily scanned. The attempt to turn this into a scandal doesn’t get far. There’s nothing suggesting that Clinton was trying to do anything more nefarious than manage her communications.
Now, that last article is mistaken where it claims that Colin Powell also set up a private server. I suspect the author doesn’t know what an email server is. Most people aren’t IT savvy. Clinton no doubt relied on technical staff to make her email work.
