Re: Confirmation checkbox needed
Sometimes it's worth skipping the confirmation checks, which is why dangerous machinery has a big red mushroom headed 'stop' button and a smaller recessed green start button under a flip cover with a key.
I don't have any more facts that the rest of you but someone during the design phase may have decided that saving seconds on the alert during a real attack was worth the risk of a false alarm, given that a real attack would have people panicking and mis-keying like crazy.
