Question

I was walking in a park packed with piles of families all around and tons of small children.
I found on the ground a turbo lighter that was very dangerous,
powerful, that shoots out a strong flame.
Heaven help us if it got into the hands of children.
Seemingly, in a case like this its place is in the trash so that no one comes to danger. It’s also not clear that it has an identifying mark, since lots of people had brought lighters to light the barbecue and this is a common industrial lighter.
True, there was some hole at the bottom, and also the color and type of the lighter, but I’m not sure that counts as an identifying mark. There also wasn’t really anywhere to put up a note about the lost item, and instinct says to throw it in the trash.
I decided my pocket was no less good than the trash,
because in the situation there, leaving it was dangerous.
Announcing it wasn’t practically possible, and it’s not clear there was an identifying mark, so instead of the trash, I’m the one who gets it.
Did I do the right thing?
