Funny how people get afraid to tell their opinions because they are scared of a future lawsuit.
You have missed the point completely.
The best advice is to
avoid the creation or display of narratives, letters and messages, comments, slogans, assertions, illustrations, symbols, etc. which, should they be made known at a later date, could reflect upon you poorly or used adversely.
Lawsuits are one thing, but don't forget job interviews, sales opportunities, application for membership or licenses, some hinds of credit approvals, and insurance coverage, the credibility of testimony or other representations, and many other things.
We have been discussing the possibility that something should be uses to describe potential
mens rea in the aftermath of a use of force incident. But that addresses only one kind of litigation. There are also discrimination suits, divorces, property disputes, fraud and embezzlement investigations, contact awards, contract compliance questions and associated claims, health and safety issues, product liability issues, and many other things.
This is by no means limited to internet posting and social media.
One more time: the best advice is to
avoid having or creating anything that, should they be made known at a later date, could reflect upon you poorly or be used adversely. And
do not rely on the likelihood that such things will remain confidential or never some to light.
Fear? No. That is all based upon
real world experience, with consequences that have ranged from the most unpleasant to the very, very costly.
