He mentions part 15 FCC, and states that it is illegal, as it doesn't comply. FCC, of course, being an American standards body. I dont know how active they are in in enforcing UK law. The sealed box, looks to be a switched mode PSU. There are rectangular holes on the side of the box. I would hazard a guess that the base unit has pegs that engage with those holes. To remove it you'd need to disengage multiple pegs. Perhaps he found it tricky to remove. If it was really anti tamper, it would be filled full of hardened resin.

A power spike will cause the unit to explode. An independent electronics expert on the internet said that. Which confirms its use as a weapon.

If you challenge this nonsense, your words can be simply taken out of context to support any crackpot theory. Or they can just as easily say that you're a shill for MI5, CIA, NSA, MFI etc. More controversy, more page views, more money in the bank.
