Did court security officer resign?

On Friday I heard that a McHenry County Sheriff's Department court security officer resigned. I'd rather not wait seven days for a FOIA response. Did he?

Was the situation a classic "resign or else" deal? And will a resignation reduce the likelihood that he will be charged with false personation of (most call it "impersonating) a peace officer? Or even a weapons charge?

There are times when people make errors in judgement. If such an error results in commission of a felony, should charges be filed?

How would something like that get swept under a rug? Either a crime was committed or it was not. Whether a person is a sworn peace officer or a non-sworn employee of the sheriff's department, shouldn't the law be applied equally as it would be against a civilian?

Should "having connections" have anything to do with not being charged?

If command personnel at the sheriff's department know of a crime that was committed, yet fail to file charges, isn't that a more serious crime? What's that called? Malfeasance of duty?

Who polices the police around here?
