This incident opens a wider topic that I believe could be a huge topic, if properly investigated.
I recommended "a money laundering investigation", and provided an example in Watchtower's own literature of their policy of getting money out of a country: "In one suitcase, soldiers found a large sum of money. It had been withdrawn from the Society’s bank account two days earlier, as it was feared that perhaps the account would be frozen." (yb97 p. 121) An investigation WOULD reveal money being funnelled back to USA; where else would Watchtower want it to go but to themselves? Does $7,500 in case meet the requirements for money laundering? Yes it does. Here's a link to the current EU law on money laundering: https://eur-lex.europa.eu/legal-content/EN/TXT/?qid=1434973778537&uri=CELEX:32015L0849 - for example point (6):
The use of large cash payments is highly vulnerable to money laundering and terrorist financing. In order to increase vigilance and mitigate the risks posed by such cash payments, persons trading in goods should be covered by this Directive to the extent that they make or receive cash payments of EUR 10 000 or more. Member States should be able to adopt lower thresholds
Any group - religious or not - collecting "contributions" for a cause, avoiding paying tax on the "income" and avoiding producing accounts, who are then covertly handing over those collected funds to a banned organization outside the national borders of the country SHOULD - I repeat SHOULD - be investigated for money laundering.
I encourage the lawful and reasonable investigation into Watchtower's finances, which by their own declaration in court is over $1 billion, and by their own internal accounts video meeting is estimated at raking in over $2 billion annually - TAX FREE!
