(February 1939 - The 2nd funniest thing is the writing of maybe as "may be" I love it!)
There are two scenarios I see here. In one, you are a squinty punk who pulls the trip on a fire alarm that ensnares you until a cop twirling a baton and sporting an Irish accent approaches saying, "Toy! Toy! What's all this then?" In the other, the same cop enters the burnt ruins of a building, twirling a baton, only to find a charred corpse dangling from the fire alarm, "Toy! Toy!" He says, "What's all this then?" Can't see much of a difference.
If there's a chance that a device can be used for something wrong, then a few people wrongly trapped isn't such a small price to pay. It's amazing that this logic still persists in most consumer electronics today.
