Re: Security Theatre
"They claim so it's not "manually" operated."
That indicates that either they are incredibly stupid or they think the rest of us are. How many people 'manually operate their alarm to wake themselves up? They don't! They set the alarm for the required time and the device does the rest. IIRC the thinking about the Brighton bomb in 1984 was planted at least weeks before and the timer was set. As you say, this is just theatre, albeit at an absurdly low level of credibility.
