I remember reading about this practice about 15 or 20 years ago. It is not new.
The public should respond to the threat by staying home. Problem solved.
You are correct. I represented a couple of clients 20 years ago who got nailed like this outside a Bruce Springsteen concert. The plaintiff's lawyers screwed up by naming Springsteen personally as a plaintiff along with the merchandizing company. I immediately responded with a Notice of Deposition directing Springstten to appear at my office the following month to have his deposition taken. The plaintiff's lawyers tried to stop it but the Judge (who was enjoying our tactics in the case) kept it on. The case was dismissed the day before the deposition. (as I knew it would be)
There was a movie made about pre-crime wasn’t there?
.....it is not new....
I did this back in the late 1970’s to protect my band clients. Bootleggers sold illegal, inferior merchandise all around concert sites and paid the bands nothing. We got federal injunctions under the copyright, service mark and trade mark laws and Federal Marshals enforced it. It worked, but you had to get separate injunctions for each locality.
