According to the report, they were arrested for having allegedly forged the paperwork of their Corona tests to be allowed entry into Israel. They were all detained and their telephones and passports confiscated. 

I can understand getting fake vaccination documents. I can understand forging serology tests, maybe to get out of quarantine.

I don't understand why someone would forge a Corona test, unless they currently have Corona (and how would they know that without the test anyway, unless they were actually sick which does not seem to be the case). How hard is it to go get a Corona test? the entire process takes about 5 minutes - plus possibly waiting in line, which I am sure the son of a Hassidic rebbe would not have to do. What's the big deal? Why fake it?

I don't get it
