The person who made that FB comment doesn’t realize that the CIA/FBI Deep State has every comment you ever made on social media stored somewhere. All they have to do is narrow it down to time, location, ISP number, etc. Whether a crank comment or an actual relative of a jury member, this person is in a world of hurt.
Meh. There will be a hearing, and the juror will say her cousin is a Hunter-level crackhead and posts crap all the time, judge will say OK then, just making sure and that will be it.
